A mathematical problem of greatest common divisor and least common multiple The sum of two positive integers is 667, and the quotient of their least common multiple and greatest common divisor is 120

435 and 232
Where's the question????
Two numbers, their greatest common factor is 4 and their least common multiple is 84. These two numbers may be () and () or () and ()
I'm in a hurry
The greatest common factor is 4 and the least common multiple is 84. These two numbers may be (4) and (84) or (12) and (28)

Given 2Z = 1 - (conjugate complex number of Z) ^ 2, find Z - √ 2I
Let z = a + bi, then the conjugate complex of Z is a-bi
According to the meaning of the title: 2A + 2bi = 1 - (a-bi) &;
2a+2bi = 1-a²+2abi+b²
a²+2a-b²-1 + (2b-2ab)i = 0
So a & # 178; + 2a-b & # 178; - 1 = 0 and 2b-2ab = 0
So a = 1, B = √ 2
Then Z - √ 2I = 1 + √ 2I - √ 2I = 1

How to find the imaginary part of 5I out of 1-2i? I am poor in mathematics
Denominator real number, get
5i/1-2i
=[(5i)(1+2i)]/[(1-2i)(1+2i)]
=(-10+5i)/5
=-2+i
So the imaginary part is 1

Complex number (2I / 1 + I) ^ 2 =?
= (2i)²/(i+1)²
=-4/(1+2i-1)
=-4/2i
=-2i/i²
=2i
(2i/1+i)^2=-4/(2i)=2i
(2i/1+i)^2= [ 2i*(1-i) / (1+1) ] ^2 = [ i*(1-i) ] ^2 = (1+i)^2 = 1-1+2i = 2i
