Question

Helpppp meeee please and thanks

Answer 1

`\boxed{\sf \ 2√(10) \ }`

Explanation:

by definition this is
`√(a^2+b^2)` for a+bi

so in this case we need to compute

`6^2+2^2 = 36+4=40`

and then 40=4*10=
`2^2*10`

So, the correct answer is
`√(40)=2√(10)`

to note that the magnitude is always a real number so you cannot get i in this kind of answer -> you can eliminate B

The magnitude is always positive so you can eliminate D

hope this helps
