Question

What is the magnitude of 6 2i?

Answer 1

Hello,

z=6+2i
||z||=√(6²+2²)=√40=2√10

Answer 2

`2√(10)`

Explanation:

Given equation

`6 + 2i\\`

Where "i" signifies an imaginary number

We know that

`a+bi = √((a^2 + (-b)^2))`-------Eq (A)

Here ,

a
`= 6`

b
`= -2`

Substituting the given values in equation (A), we get -

`6+2i\\= √((6^2+(-2)^2) \\= √((36+4))\\ = √(40)\\ = √(4*10) \\= 2√(10)`

Hence, the values of equation is
`2√(10)`
