The minimum multiple of a number is 36, and the divisor of the number is

The minimum multiple of a number is 36, and the divisor of the number is

1,2,4,6,9,18,36

The maximum number of a number is 36. What is this number? What are all its divisors? What is the minimum multiple of this number

36
The divisors are: 1,36,2,18,3,12,4,9,6
Minimum multiple 36

The greatest divisor of a number is its smallest multiple______ (judge right or wrong)

Because: the largest factor of a number is itself, and the smallest multiple of a number is itself; so the largest divisor of a number is its smallest multiple; so the answer is: correct

If the complex Z satisfies Z2 + 1 = 0, then the point of the complex Z on the plane is symmetric

Z = I, - I, about real axis symmetry

Let Z ∈ C, then the equation (Z-2) (- 2) + (Z + 2) (+ 2) = 2 (| z2-4 | + 2) denotes a curve of? (higher 2 complex number)
Let Z ∈ C, then the curve represented by equation (Z-2) (- 2) + (Z + 2) (+ 2) = 2 (| z2-4 | + 2) is? (higher 2 complex) and the two missing (- 2 + 2 before) are conjugate complex of Z

Let z = x + Yi, (x ∈ R, y ∈ R) then
(z－2)(－2)＋(z＋2)(＋2)=4
2(|z²-4|＋2)=4
|z²-4|=0
z²-4=0
z²=4
z²=(x²-y²)+2xyi=4
x²-y²=4
xy=0
Solution
x=±2,y=0
The curve represented by is two points

If z = 2 + I / I, then | Z|=

(2-i)/5

Given the complex number Z = I (2-I), then | Z | =?
···

z=2i-i^2=1+2i
|z|=√(1^2+2^2)=√5

Find the complex Z satisfying the condition:
(1) Z + 10 / Z is a real number, and 1 < Z + 10 / Z ≤ 6
(2) The real and imaginary parts of Z are integers

Let u = Z + 10 / Z, then Z ^ 2-zu + 10 = 0
∵ u is a real number, 1

The complex Z satisfies the following conditions simultaneously
(1) The module of Z is equal to a
(2) The sum of the real and imaginary parts of Z is equal to the value of the product
If there are exactly three such Z, then a=______

a=1

If Z1 = - 1-I, Z2 = 5I, then Arg (z1 + Z2)=
Arg (z1 by Z2)=

z1=-1-i
z2=5i
z1+z2=-1+4i
tan[arg(z1+z2)]=-4
z1*z2=(-1-i)*5i=-5i+5=5-5i
tan=-1
So Arg = - 7 π / 4
