Answer:
1
Step-by-step explanation:
Using the order of operations, we know we need to start by evaluating the expression in the parenthesis, and further we need to compute 3^2 first and 3^2 = 9.
We can rewrite the expression as:
6^2 - 7(8 + 6 - 9)
Next we can add from left to right. 8 + 6 is 14, and 14 minus 9 is 5. We can rewrite as:
6^2 - 7(5)
The next step in to evaluate the power, 6^2, which is 36. Now, it can be written as:
36 - 7(5)
7 times 5 is 35, which we can replace:
36 - 35 = 1
So we get 1 as an answer.
