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.
