The greatest common divisor of 16 and 20 is______ The least common multiple is______ .

The greatest common divisor of 16 and 20 is______ The least common multiple is______ .

8 = 2 × 2 × 216 = 2 × 2 × 2 × 220 = 2 × 2 × 5, so the greatest common divisor of 8, 16 and 20 is 2 × 2 = 4, and the least common multiple is 2 × 2 × 2 × 2 × 5 = 80, so the answer is 4; 80
What is the greatest common divisor and the least common multiple of 3 and 16 and 24
Greatest common divisor 3
Least common multiple 48
Given the complex number Z1 = a + bi, Z2 = b-ai Z1, Z2 corresponds to the point Z1 on the complex plane, Z2 proves that the vector OZ1 is perpendicular to the vector oz2
The real part of the complex plane corresponds to the x-axis and the imaginary part to the y-axis
So the vector OZ1 can be expressed in coordinate form (a, b)
Similarly, vector oz2 = (B, - a)
Two vectors a = (x, y), B = (m, n) are perpendicular if and only if XM + yn = 0
And AB-Ab = 0, so the vector OZ1 is perpendicular to the vector oz2
Do black English heroes add s to their plural forms?
Es
+Es, how to remember: nouns end with - O, living plus - es, inanimate plus - S
It should be all plus es
Plus es
Es
The words ending with e i o u E ch sh th are usually added with ES!
Given the complex number Z1 = m + (4-m2) I (m ∈ R), Z2 = 2cos θ + (λ + 3sin θ) I (λ ∈ R), if Z1 = Z2, find the value range of λ
∵ Z1 = Z2, ∵ from the necessary and sufficient condition that two complex numbers are equal, M = 2cos θ 4 − M2 = λ + 3sin θ ∵ λ = 4-4cos2 & nbsp; θ - 3sin & nbsp; θ = 4sin2 & nbsp; θ - 3sin & nbsp; θ = 4 (Sin & nbsp; θ - 38) 2-916, ∵ Sin & nbsp; θ ∈ [- 1,1]. From the properties of quadratic function, we know that λ ∈ [- 916,7] ∵ the range of λ is [- 916,7]
What's the plural of "hero"? "Heros" or "Heroes"? You must be very sure to answer!
heroes~
It's heroes
heroes
Given the complex z = √ 2I (3 + 4I) / (√ 3 - √ 2I) &# 178;, then the module of complex Z is
|z|=√2*|3+4i|/|√3-√2i|²
=√2*5/（√5）^
=√2.

I wish you progress in your study and make progress! If you are satisfied with the answer, please remember to adopt it, thank you! (*^__ ^ *
The plural is itself
heroes.
M belongs to R complex, z = [M (M + 2) / (m-1)] + (m ^ 2 + 2m-3) I when m is a value, Z belongs to R
If Z belongs to R, the imaginary part is 0
So M & sup2; + 2m-3 = 0
m=-3,m=1
