Question

What is the modulus of 2-3i?

Answer 1

this would be sqrt(2^2 + (-3(^2)   = sqrt 13

Answer 2

`√(13)`

Explanation:

WE need to find the modulus of 2 - 3i

We are given with complex number 2 - 3i in the form of a+ib

a= 2 and b = -3

To find modulus we use formula

`√(a^2 + b^2)`

Replace a=2 and b = -3

`√(2^2 + (-3)^2)`

`√(4+9)`=
`√(13)`
