Answer:
4
Explanation:
This is an order of operations problem. II'll use using PEMDAS here:
- P: Evaluate expressions in parenthesis first
- E: Evaluate terms with exponents
- MD: Evaluate multiplication and division from left to right
- AS: Evaluate addition and subtraction from left to right
Parenthesis first. The first expression in parenthesis is already as simplified as it gets, so up next is the second one:
There are no parenthesis and there are no exponents, so do the multiplication first.
Back to the original expression and we now have:
Exponents comes next:
Now we have:
Multiplication comes next:
Finally, addition.
