Since there are no parentheses or exponents, division is our first step.
First, simplify the parentheses. Since there are many operations in the parentheses, follow the order of operations inside them, too. In this problem, division would come first.
In this problem, treat the numerator and denominator like they are in separate parentheses, and the fraction bar as a division sign. You could rewrite this problem as: . Now simplify each set of parentheses using the correct order of operations.
Here, we have two sets of parentheses, the regular ones and the brackets. Simplify the innermost set first.
