Answer 3

To solve the expression (-5)² - 9, you simply need to follow the order of operations, which is PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Let's break it down step by step:

Step 1: Evaluate the exponent. (-5)² means raising -5 to the power of 2. (-5)² = (-5) × (-5) = 25

Step 2: Subtract 9 from the result obtained in Step 1. 25 - 9 = 16

So, the solution to the expression (-5)² - 9 is 16.
