Question

Evaluate the expression $-2·{(-3)}^2$.

Answer 1

Step 1: Write ${(-3)}^3$ as a continued multiplication.

$=-2·(-3)(-3)(-3)$

Step 2: Solve the multiplication.

Multiplication can be done in pairs.

$\left[\right(-2\left)\right(-3\left)\right]\left[\right(-3\left)\right(-3\left)\right]$

Step 3: Solve the parenthesis.

$=\left(6\right)\left(9\right)=54$

Hence the answer is $54$.
