Question

If z = sqrt2 - 2i, then |z| = _____.

Answer 1

sqrt 2
sqrt 6
3
6

Answer 2

what do you think it is?

Answer 3

I have no clue

Answer 4

give me a sec my computer a little slow,

Answer 5

to be honest I dont really know but I think it is 3 just from what i see

Answer 6

They gave you \(\Large z = \sqrt{2} - 2i\) right?

Answer 7

yeah

Answer 8

so

a = sqrt(2) ---> a^2 = 2
b = -2 ---> b^2 = 4

|z| = sqrt( a^2 + b^2 )
|z| = sqrt(2 + 4)
|z| = sqrt( 6 )
