Question

Use the rules for order of operations to 8^(2)+7(-2-5)+3

Answer 1

To simplify the expression 8^(2)+7(-2-5)+3, follow the order of operations.

Step-by-step explanation:

To simplify the expression 8^(2)+7(-2-5)+3 using the rules of order of operations, follow these steps:

1. First, calculate the exponent. 8^(2) is equal to 64.
2. Next, simplify the parentheses. -2-5 is equal to -7.
3. Now, multiply 7 by the result of step 2. 7(-7) equals -49.
4. Finally, add the results of steps 1 and 3, and then add 3. 64 + (-49) + 3 equals 18.

Therefore, the expression 8^(2)+7(-2-5)+3 simplifies to 18.
