What is the value of (3 + 5)²?

To determine the value of ( (3 + 5)^2 ), you first need to simplify the expression inside the parentheses. Adding the numbers together gives:

[

3 + 5 = 8

]

Now, you take this result and square it. Squaring a number means multiplying the number by itself:

[

8^2 = 8 \times 8 = 64

]

Thus, the value of ( (3 + 5)^2 ) is 64, which corresponds to the choice provided.

This method involves clearly performing the operations in the correct order, following the mathematical rules of parentheses and exponents. Understanding how to structure such calculations helps in approaching similar problems effectively.
