Answer
$\left[(7-10)\cdot 2\right]^2$;
The simplified expression is equal to 36.
Work Step by Step
Subtract 10 from 7:
$7 - 10$
Multiply the difference by $2$:
$(7-10) \cdot 2$.
Square the product:
$\left[(7-10)\cdot 2\right]^2$
The order of operations states that to simplify the expression, the first step is to simplify the expression inside the parentheses.
Thus,
$\left[(7-10)\cdot 2\right]^2=(-3 \cdot 2)^2=(-6)^2$
The next step is to apply the exponent:
$(-6)^2=36$
