What is the value of 4² + 2²?

To find the value of ( 4² + 2² ), you first calculate each square individually.

When you square 4, you multiply 4 by itself: [

4² = 4 \times 4 = 16. ]

Next, you square 2: [ 2² = 2 \times 2 = 4. ]

Now that you have both squares, you can add them together: [ 16 + 4 = 20. ]

Thus, the correct value of ( 4² + 2² ) is 20. This demonstrates the process of squaring numbers and then performing addition, solidifying understanding of basic arithmetic operations involving exponents and whole numbers.
