Negative brackets to the 100th power plus negative brackets to the 101st power Thank you, brother and sister


(-2)^100+(-2)^101
=-2^100



Minus 2 times bracket-0.5 to the 100th power + 8 to the 101st power × (- 0.125 to the 100th power)


[-2*(-0.5)]^100+8^101*(-0.125)^100
=1^100+8*8^100*0.125^100
=1+8*(8*0.125)^100
=1+8*1^00
=1+8
=9



The definition field of y = log base 2 real number (√ x-1) - 1 is (compulsory Mathematics)


The first is the log function, the true number must be greater than 0, that is (√ x-1) - 1 > 0
Secondly, under the root sign, the value is also greater than 0, that is, X-1 > = 0
To sum up, its definition domain is: x > 2

Why is x0 = 0 when f (x) is expanded into a power series


X0 = 0 is just a case, f (x) = ∑ an (x-x0) ^ n is a general form, x0 = 0 is a special form, and expanding the function into a power series of X is just expanding the function into the form of (x-0)



How many millimeters is 2.56 meters?
Urgent. Thank you!


2560mm



If the function y = - x2-4mx + 1 is a decreasing function on [2, + ∞), then the value range of M is___ .


The function y = - x2-4mx + 1 is a quadratic function with an opening downward. The function is monotonically decreasing on [- 2m, + ∞). When x ∈ [2, + ∞), the function is decreasing, that is, the solution of - 2m ≤ 2 is m ≥ - 1, so the answer is m ≥ - 1



What's the product of the sum of 9 plus 3 / 4 divided by 1 / 4 multiplied by 5 / 6?


9+(3/4/1/4)*5/6
=(9+3)*5/6
=12*5/6
=10



In the first year of junior high school, we merge the similar items,
Given the quadratic power of (A-2) + the quadratic power of (B + 1) = 0, find the quadratic power of polynomial 3a, the quadratic power of B + AB, the quadratic power of 3a, the quadratic power of B + 5ab + AB, the quadratic power of 4AB + 2 / 1ab


The second power of (A-2) + the second power of (B + 1) = 0
a-2=0 a=2
b+1=0 b=-1
The second power of 3a is B + the second power of ab - the second power of 3a is B + 5ab + the second power of ab - the second power of 4AB + 2 / 1ab
=5/2ab^2+ab
=5/2*2*1+2*(-1)
=5-2
=3



Poems about wine and tea
What I learned in junior high school


Chanting the twelve rhymes of tea (Tang Qiji, five character rhythms) a hundred grasses give way to the spirit, and the merit comes first. It is sweet to spread all over the world, and is famous for its popularity. It comes from no wild geese in spring, and there are warblers in the valley when it comes to harvest. The title comes from Zeguo and contributes to the capital of Qin Dynasty, The pagoda poem "one word to seven word poem · tea" (Tang Yuanzhen) -- - tea, fragrant leaves, tender buds, admirers, love monk's family, -- grinding and carving white jade, weaving red yarn, -- frying yellow pistil color, bowl turning dust flower. After night, invite to accompany the moon, "To tea" (Tang · sun Shu) small pavilion cooking tea, sparse curtain under the jade ditch; lights turn out the tripod, hairpin shadow sink Ou; maidservant hold away spring sleepiness, personally taste scattered Twilight sorrow; chanting poetry for a long time, the moon turns to the evening dressing house. "Summer leisure" (Tang · Zhang Ji) more sick, less flattering, leisure for another year, The day after tomorrow, the insect flies late. At this time, the dream is far away, and I don't feel that I am at the edge of the mountain. I am with the purple buds and white pistils of Shengshan Chaling (Zhang Ji of Tang Dynasty) in weikaizhou. I see my family picking them, and I usually touch them. Shangshuhui waxy tea (Xu Yin of Tang Dynasty) is in Wuyi, where the spring is warm and the moon is round, and new buds are picked to present the earth immortals, "Taste tea in the gorge" (Zheng Gu of Tang Dynasty) is full of new English, and taste it by fire in Xiaojiang garden. Wu Seng says that the crow mountain is good, but the old Shu people don't boast about the fragrance of bird's beak. The half Ou of the whole seat is light green, and several pieces of it are light yellow. The sick people of lumen don't go back, and their thirst for wine is even longer. Taste tea (Liu Yuxi of Tang Dynasty) is afraid of the fragrant cluster of hawk's beak buds, Lao Lang was sent to the immortal's family. Tonight, there is the moon on the Xiangjiang River, which is full of flowers. On the ninth day, he had tea with Lu chushiyu (Tang Jiaoran). On the ninth day, jiurishan monastery and Dongli chrysanthemum are yellow. Most common people drink wine, but who can help the fragrance of tea, This thing is pure and noble, and people often deceive themselves when they drink. When they look at the night between the birzhuo urn and smile at Tao Qianli, Cui Hou's meaning is not his own, and his crazy song is amazing. Who knows that the tea way is true, only Dan qiude is like this; Mingpo (Tang · Lu Xisheng) in February, the valley of the mountain is rainy, and Banpo is full of fresh tea. In spring, he is sick and thirsty, and he is fond of picking and frying new buds. The Phoenix chariot of Huzhou Gongbao new tea (Tang · Zhang Wengui) is half drunk in spring, and the fairy e is in the water, and the curtain is open. The peony flowers are smiling, It's said to play Huzhou purple bamboo shoots. Tea fried with Luobei wild spring in Mengjiao (Tang · Liu Yanshi) is made of fine powder. It's over the bamboo shoots and fried on the cold river bank. I'm afraid it's good and grassy. I'll touch everything with my hands. I'll knock on the stone to get fresh fire and leave the spring to avoid fishy scales. I'll pick up the nest salary with the wind. The clean color is cool, floating and attentive, "New tea chant to Xichuan Xianggong's twenty third uncle and doctor's twenty second uncle" (Tang · LuLun) three presents Penglai first taste, day tune Golden Tripod read fragrance. Store jade half cake, send to a Lian title several lines. "Tea banquet with Zhao Ju" (Tang · Qianqi) bamboo forget to talk about purple tea, all win feather guest drunk Liuxia, The sound of cicadas in a tree is slanting. Drinking tea with Kang Jushi in qingshantan (Lingyi of Tang Dynasty), sitting in the smoke and white clouds of yequan, drinking fragrant tea and loving this mountain. The boat under the rock can't bear to go, and the water flowing in Qingxi is murmuring at dusk. Qin tea (Bai Juyi of Tang Dynasty) is a kind of self willed life. Since leaving the official post, he has been drunk in spring, and he has no time to study tea, The old tea is Mengshan. The poor travel together, the long travel together, who says that I have no future today. At night, I heard that Jia Changzhou and Cuihu had a banquet in the tea mountain Pavilion (Tang · Bai Juyi). At night, I heard that Jinghui had a tea mountain. At night, Zhucui's singing bells were all around me. The plate was divided into two states. In front of the lamp, I wrote a spring "summer and day's work" (Tang · Liu Zongyuan). I was as drunk as wine in the heat of Southern Zhou, and I was almost asleep to open the northern Zhou, Today, by the side of the temple, tea smoke is blowing gently. The milk of the tea song of the Taoist priest in Xiling (Tang · Wen Tingyun) splashes through the stone veins, green dust worries about the color of the grass in spring. The flowers in the stream are fragrant, and the mountains and the moon are straight. The fairy man's white fan is frost bird plume. He reads Huang Ting Jing at night, Tea Poetry (Zheng invitation of the Late Jin Dynasty) is full of tender buds. I call it grass, Chinese and English. The mortar and smoke are pounded in the night, and the cold stove cooks in the snow. However, green peanuts are common. They are most precious, and can make you sleep and think clearly
