Leroy tried to evaluate an expression. Here is his work:42+22−4×6÷3×262−4×6÷3×2 {Step 1}36−4×6÷3×2 {Step 2}36−24÷3×2 {Step 3}36−8×2 {Step 4}36−16 {Step 5}20 {Step 6}Is Leroy's work correct?(A)No, Leroy made a mistake going from the given expression to Step 1. Leroy should have squared 4 and 2 instead of adding. The order of operations says to evaluate exponents before you add.(B)No, Leroy made a mistake going from Step 3 to Step 4. Leroy should have multiplied 3 and 2 before dividing. The order of operations says to multiply before you divide.(C)Yes, Leroy's work is correct.

Evaluate Exponents: Leroy starts by evaluating the expression 42+22−4×6÷3×2. First, we need to handle the exponents. 42=16 and 22=4.
Add Exponents Results: Next, add the results of the exponents: 16+4=20.
