Is 16 the correct answer?

no, it's not. The correct answer is 34

Step-by-step explanation:

You were almost close! However, a² is equal to a × a or (a)²

I mean by

take (-5)² and -5² for example

the one in parentheses is equal to -5 * -5 which is 25  (you are taking the who -5 and squaring itself)

while the one without the parentheses is like -(5 * 5) which is -25

Therefore, this will be like |(-5)² + (3)²|

Simplify:

|25+9|= 34

Hope this helps!
