54

#### Explanation:

When evaluating expressions with $\textcolor{b l u e}{\text{mixed operations}}$ there is a particular order that must be followed.

Follow the order as set out in the acronym PEMDAS.

$\Rightarrow \left({6}^{2} - 9\right) = \left(36 - 9\right) = 27 \leftarrow \textcolor{red}{\text{bracket with exponent}}$

$\Rightarrow 2 \left(27\right) = 2 \times 27 = 54 \leftarrow \textcolor{red}{\text{ then multiplication}}$
