Work Step by Step

In order to use your calculator for these problems, make sure to always put parenthesis around any fraction when the whole fraction is raised to a power. (For instance, type in $(2/3)^3$ and not $2/3^3$. Also, when considering the denominator of a fraction, always use parenthesis when just the denominator is raised to a power. For instance, write $1/(2^{-4})$ instead of $1/2^{-4}$.
