Answer
256
Work Step by Step
We follow the instructions to plug 2 in for a and 4 in for b. Thus, we obtain:
$ (4\times2)^{3} \div (4-2)$
We follow order of operations, so we first consider everything inside of the parenthesis, then the exponent, and finally division. Thus, we find:
$8^{3} \div 2 \\\\ = 512 \div 2=256$
