Question

Petey calculated |5+13i|

Answer 1

`|5+13i|=√(194)`

Explanation:

The given expression is
`|5+13i|`.

This is a complex number expression.

The absolute value of the complex number means the magnitude of the complex number.

Recall that;

`|a+bi|=√(a^2+b^2)`

This implies that:

`|5+13i|=√(5^2+13^2)`

`|5+13i|=√(25+169)`

`|5+13i|=√(194)`
