Answer 2

Answer:

$|5+13i|=\sqrt{194}$

Step-by-step 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;

$|a+bi|=\sqrt{a^2+b^2}$

This implies that:

$|5+13i|=\sqrt{5^2+13^2}$

$|5+13i|=\sqrt{25+169}$

$|5+13i|=\sqrt{194}$
