Answer 8

It said -18 is incorrect?
The answer that you submitted, −18, is incorrect.
It appears as though you have forgotten to apply the Negative Exponent Rule. Because the exponent given in the problem is negative, the Negative Exponent Rule must be applied, and some of the final answer belongs in the denominator of a fraction.
