Start with

$4(3^3-8) \div 2$

Exponents have the highest priority, so we evaluate 3 cubed first:

$4(27-8) \div 2$

Next, we have to solve parenthesis first: we have 27-8 = 19, so the expression becomes

$4 \times 19 \div 2$

Multiplications and divisions have the same priority, so we perform them as they appear: $4 \times 19 = 76$ , so the expression becomes

$76 \div 2 = 38$
