SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Write the given expression
STEP 2: Explain the order of operations
The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Parentheses are also known as brackets.
STEP 3: Evaluate the expression
Using PEMDAS means that we solve the parenthesis first
Hence, the evaluation of the expression gives 64
