What is the value of (3² + 4²)?

  1. 7

  2. 12

  3. 25

  4. 30

The correct answer is: 25

To find the value of (3² + 4²), we first need to calculate each square separately: 3² means 3 multiplied by itself, which is equal to 9. 4² means 4 multiplied by itself, which is equal to 16. Next, we add the two results together: 9 + 16 equals 25. Therefore, the expression (3² + 4²) evaluates to 25, making the correct answer C. Understanding this involves recognizing that squaring a number involves multiplying the number by itself, and adding the results of those squares gives us the final value we are looking for.
