Find the 5th power of - a square A / the 8th power of 2 - A / the 11th power of 3 A / 4 --- the nth formula is?


The (3n-1) power of a / n



-The square of a, the 5th power of 2 / A, the 10th power of 3 / A, and the 17th power of 4 / A. how many is the nth formula


(- 1) n times (A / N) n + 1 power, sorry, write your own formula, I can't type it



There are two barrels of oil. The weight of the first barrel is 1.2 times that of the second barrel. If you take 6kg from the first barrel and put it into the second barrel, the two barrels of oil are the same weight
How many kilos each of the original two barrels of oil


Suppose the second barrel of oil had x kg
1.2x-6 = x+6
0.2x = 6+6
x = 12÷0.2
x = 60
First barrel: 60 × 1.2 = 72 (kg)



Why is the point where f (x) = | X-2 | e ^ x derivative does not exist x = 2?


X = 2 is the point of the curve turning the dead corner, and is the non derivable point. When x > 2, f (x) = (X-2) e ^ x, f (2) = 0lim (Δ X -- > 0 +) [f (2 + Δ x) - f (2)] / Δ x = LIM (Δ X -- > 0 +) [(2 + Δ X-2) e ^ (2 + Δ x) / Δ x = LIM (Δ X -- > 0 +) [e ^ (2 + Δ x)] = E & # 178; x0 -) [f (2 + Δ x) - f (2)] / Δ x = LIM (Δ X -- >



First question (solving equation): 36.2-3 (x-1) = 16.4 second question (solving equation): 6 (x-3) = 2 (x + 0.5)


Question 1: 36.2-3 (x-1) = 16.4 question 2: 6 (x-3) = 2 (x + 0.5) 36.2-3x + 3 = 16.4 6x-18 = 2x + 1 solution 3x = 22.8



A cylindrical tube, its inner diameter is 0.6 meters, such as the speed of water flow is 1 meter per second, how many cubic meters of water flow through the gate in one minute?


3.14*(0.6/2)*(0.6/2)*1*60
=3.14*0.09*60
=0.2826*60
=16.956
A: the amount of water flowing through the gate in one minute is 19.956 cubic meters



X ^ 2 is the high order infinitesimal of X, and 1 / X is the low order infinitesimal of X. then what order is 2 ^ x?


X tends to and 0,2 ^ x is the infinitesimal of low order of X



Find the law: half, one third, five sixths, (), twelve sixths, () (0.3,4), (0.6,9), (1.2,16), (), (4.8,)


Find the rules: half, one third, five sixths, (seven sixths), twelve sixths, (nineteen sixths)
(0.3,4),(0.6,9),(1.2,16),(2.4,25),(4.8,36)



Number reasoning: 1,7,7,9,3, ()


Multiply by mantissa!
1 * 7 = 7 --- mantissa is 7
7 * 7 = 49 --- mantissa is 9
7 * 9 = 63 --- mantissa is 3
9 * 3 = 27 --- mantissa is 7
Multiplication takes mantissa, so () = 7



There are three forces in common, which are 14N, 10N and 5N respectively. What is the minimum value of the resultant force


10 plus 5 equals 15, which means that these two forces produce a maximum force of 15 n. if the angle is adjusted so that their resultant force is 14 n, then they are just in balance with the third force, so the resultant force is 0
