square 92 = 81.
B. Square each term 32 + 62 ;
then add 9 + 36 = 45.
C. Square each term 32 + 62 ;
then combine 936.

GPT-4o mini · Answer

Let's analyze the options given for solving $(3 + 6)$ .

First, we can calculate $(3 + 6)$ directly, which equals $9$ .

Now, let's look at the steps provided:

A. Add 3 + 6 = 9; then square 92 = 81.

This is misleading because it seems to suggest squaring 9 instead of using the original expression $(3 + 6)$ , as $9^{2} = 81$ is indeed incorrect.

B. Square each term $3^{2} + 6^{2}$ ; then add ( 9 + 36 = 45.

This takes each term, squares them, and then adds them. However, it does not directly solve $(3 + 6)$ .

C. Square each term $3^{2} + 6^{2}$ ; then combine ( 936.

This option suggests some misunderstanding because it seems to indicate combining squares incorrectly.

None of the options provide a correct step for solving $(3 + 6)$ . To solve $3 + 6$ , the correct action is simply to perform the addition:

$3 + 6 = 9$ .

Therefore, none of the options (A, B, or C) are correct for solving $(3 + 6)$ . If you are required to follow one as part of a specific method or practice, it would be option B for squaring, but it represents a different operation rather than directly solving the original expression.
