Given Z2 (the square of Z) = 5-12i, find z-pull
By the way, can you tell me the formula?
Let z = a + bi
z^2=a^2+2abi-b^2
a^2-b^2=5
2ab=-12
a=-6/b
36/b^2-b^2=5
b^4+5b^2-36=0
b^2=4
b=2,a=-6,z=-6+2i；
I = 2-6, or Z = - 6

Plural calculation
（1-√3i）^15/(1-i)^30+(√3+i)^15/(1+i)^20
The original formula = (1 - √ 3I) ^ 15 / (- 2I) ^ 15 + (√ 3 + I) ^ 15 / (2I) ^ 10 = [(1 - √ 3I) / (- 2I)] ^ 15 + (√ 3 + I) ^ 15 * 2 ^ 5 / [2 ^ 5 * 2 ^ 10 * (I) ^ (8 + 2)] = (√ 3 + I) ^ 15 / (2) ^ 15 + (√ 3 + I) ^ 15 * 32 / [- 2 ^ 15] = - 31 (√ 3 + I) ^ 15 / (2) ^ 15 = - 31 [cos π / 6 + isin π / 6) ^ 15 = - 31 [cos15 π /

On the concept of mathematical complex number
If Z1 = 2 + 2I; Z2 = 1 + 2I
Is Z1 > Z2 Tenable?
However, there seems to be such a saying: the imaginary number can not be compared in size, but if its imaginary part is the same, can it be compared in size?
You're right. Imaginary numbers can't be compared in size
So if it is an imaginary number, then z1-z2 > 0, Z1 > Z2 cannot be deduced

What question do you want to ask? Generally speaking, plural nouns can be changed by adding - s after them. However, some words have different endings, and the ways to change plural are also different. For example, for words ending with - s, - Z, - x, - SH, - CH, etc., plural nouns should be changed by adding - es. for example, bus → buses; quiz → quizes; fox → foxes; m
We all know that the square of Hai is - 1, so how much is the cubic fourth power and the fifth power of I pushed down all the time? For example, how much is the 63rd power of I? Is there a trick
i^1=i
i^2=-1
i^3=-i
i^4=1
i^5=i
i^6=-1
i^7=-i
i^8=1
...
I^n
When n = 4K (k = 0,1,2,...), I ^ n = 1
When n = 4K + 1, I ^ n = I
When n = 4K + 2, I ^ n = - 1
When n = 4K + 3, I ^ n = - I
63=4*15+3
i^63=-i
English plural sentence to singular sentence
He is a boy. Singular they are boys. Plural I am a boy. Singular we are boys. Plural she is a girl. Singular they are girls. Plural I've solved a book. Singular I've solved many books last night
they→he\she\it their→his\her\its them→him\her\its
we→I ours→my us→me
have→has are→is\am do→dose
Plural nouns have corresponding singular nouns, and then corresponding to change
Hope to help you
What about the sentence? Question: no sentence, rules
Please come in, on the related calculation of mathematical complex number
(the square of X - 5x + 6) + (Y - 4) I = 0, find the value of X, y
The square of x-5x + 6 = 0, y-4 = 0
Question: why can't the square of X - 5x + 6 be equal to - (y + 4) I?
It's not that it can't be equal, it's equal, but it's meaningless to solve the problem
Because the plural is in the same form
a+bi
So a + bi = 0
A = 0, B = 0
So you can get the equation and the answer
