## Elementary Algebra

To solve the expression, we simplify the expression within the parenthesis first and then raise the resulting expression to the power of 2. Note, because of order of operations, we raise numbers in parenthesis to their exponent before we subtract: $(2^{2}-2-2^{3})^{2}$ =$(4-2-8)^{2}$ =$(2-8)^{2}$ =$(-6)^{2}$ =$36$
