Start with

[tex] 4(3^3-8) \div 2 [/tex]

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

[tex] 4(27-8) \div 2 [/tex]

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

[tex] 4 \times 19 \div 2 [/tex]

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

[tex] 76 \div 2 = 38 [/tex]
