-8^2 • 3/4 - 10
Follow the order of operations to solve this.

Step 1: Exponents
Since there are no parentheses, the first step for us is exponents.
-8^2
Negative numbers with positive exponents are the same as positive numbers with positive exponents, except the answer is negative as well.
-8^2 = -64
Now we have: -64 • 3/4 -10

Step 2: Multiplication
-64 • 3/4
First, let's convert 3/4 to a decimal.
3/4 = 0.75
Now, just multiply -64 by 0.75.
-64 • 0.75 = -48
Now we have: -48 - 10

Step 3: Subtraction
-48 - 10
When subtracting from a negative, add like positives then put a negative sign in front of the answer
-48 - 10 = -58
Now we have the -58

The answer to -8^2 • 3/4 - 10 is -58.
