Answer
$\left[(9-11)\cdot 2\right]^4$;
The simplified form of the expression is equal to $256$.
Work Step by Step
Subtract 11 from 9:
$9-11$
Multiply the difference by $2$:
$(9-11) \cdot 2$
Raise the product to the fourth power:
$\left[(9-11)\cdot 2\right]^4$
The order of operations states that to simplify the expression, the first step is to simplify the expression inside the parentheses.
Thus,
$\left[(9-11)\cdot 2\right]^4=(-2 \cdot 2)^4=(-4)^4$
The next step is to apply the exponent:
$(-4)^4=(-4)(-4)(-4)(-4)=256$
