We are going to have to use order of operations (often called "PEMDAS"), which says that expressions should be simplified in the following order:
- Parentheses
- Exponents
- Multiplication/Division
- Addition/Subtraction
First, we can see that there are some parentheses, which we will need to take care of first. Inside the parentheses is , which simplifies to 6. Our expression is now:
Second, we see that there is an exponent. , so our expression is now:
Third, we have multiplication, . , so our expression is now:
Fourth, we complete the addition and subtraction:
Our answer is 80.
