$18$

#### Explanation:

There are 2 terms. Each will simplify to a single answer which can be added or subtracted in the last step.

Within each term: brackets are done first, then powers and roots and then multiply and divide.

${\left(\textcolor{red}{8 - 4}\right)}^{2} + \textcolor{b l u e}{8 \div 4}$

$= \textcolor{red}{{\left(4\right)}^{2}} \textcolor{b l u e}{+ 2}$

$= 16 + 2$

$= 18$
