    \[\frac{3^{-3}+3^{-4}}{3^{-5}}\]?

    probably simplest to break it into two fractions \[\frac{3^{-3}}{3^{-5}}+\frac{3^{-4}}{x^{-5}}\]

    when you divide if the bases are the same you subtract the exponents. be careful when you subtract, because you are subtracting a Negative number. \[\frac{3^{-3}}{3^{-5}}=3^{-3-(-5)}=3^{-3+5}=3^2\]
