Hello!
The topic we should review for this problem is Order of Operations.
What is Order of Operations?
Order of Operations is a rule that identifies which part of an equation should be simplified first.
You might've heard of PEMDAS, where;
P for Parentheses, always first unless there's an exponent inside.
E for Exponent, simplified after the Parentheses.
M or D - Multiplication or Division after the Exponent(s).
A or S - Addition or Subtraction after Multiplication or Division.
First we know that there's an Exponent inside the Parentheses, so we must evaluate that number first.
Next, evaluate what's in the Parentheses.
Our correct answer is 32.
We are asked what mistake did Raquel make, and what's the correct simplified version of the expression.
1a.) Raquel's mistake is combining unlike terms. It's impossible to combine together a natural number (5) and an exponential number. (3²)
1b.) The correct simplified version of the expression is represented here;
