Evaluate: (5² - 3²)

Evaluate: (5² - 3²)

• A. 16
• B. 12
• C. 20
• D. 10

Answer: (A)

To evaluate the expression (5² - 3²), we start by calculating the squares of the numbers involved. First, compute 5²: 5² = 5 × 5 = 25. Next, compute 3²: 3² = 3 × 3 = 9. Now, subtract the square of 3 from the square of 5: 25 - 9 = 16. Thus, the result of the expression (5² - 3²) is 16. This confirms that the correct answer is indeed 16. The reasoning follows the order of operations and basic arithmetic principles, applying the rule for evaluating exponents followed by subtraction.
