Answer:
17
Explanation:
To solve the expression 81 - 8 to the 2nd power, we need to follow the order of operations, also known as PEMDAS.
Step 1: Evaluate the exponent first.
8 to the 2nd power means 8 multiplied by itself: 8^2 = 8 * 8 = 64.
Step 2: Subtract the result of the exponent from 81.
81 - 64 = 17.
So, the expression 81 - 8 to the 2nd power equals 17.
In summary:
81 - 8^2 = 81 - 64 = 17.
