To solve the expression using the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), we follow these steps:
Step 1: Simplify within parentheses.
4 power of 2 = 4^2 = 16
8 + 7(16 - 3)
Step 2: Simplify within parentheses.
16 - 3 = 13
8 + 7(13)
Step 3: Perform multiplication.
7 * 13 = 91
8 + 91
Step 4: Perform addition.
8 + 91 = 99
Therefore, 8 + 7(4^2 - 3) simplifies to 99.
