1) Bentuk sederhana dari
$\frac {4x^{- \frac {2}{3}}y^{\frac {4}{5}}z^{- \frac {5}{2}}}{5z^{- \frac {3}{2}}x^ {- \frac {5} {3}}y^{- \frac {1}{5}}}$

2)$ \frac {^6 \log 27. ^{\sqrt3} \log 36 -^4 \log \frac {1}{64}}{^6 \log 36 - ^6 \log 6 \sqrt 6 }$

Pembahasan:
1)  $\frac {4x^{- \frac {2}{3}}y^{\frac {4}{5}}z^{- \frac {5}{2}}}{5z^{- \frac {3}{2}}x^ {- \frac {5} {3}}y^{- \frac {1}{5}}} \\ \text {bilangan} = \frac {4}{5} \\ \text {x} \rightarrow \frac {x^{-\frac {2}{3}}}{x^{- \frac {5}{3}}}=x \\ \text {y} \rightarrow \frac {y^{\frac {4}{5}}}{y^{- \frac {1}{5}}}=y \\ \text {z} \rightarrow \frac {z^{\frac {5}{2}}}{z^{- \frac {3}{2}}}=z \\ \text {hasilnya} \\ \frac {4}{5}xyz$

2) $\frac {^6 \log 27. ^{\sqrt3} \log 36 -^4 \log \frac {1}{64}}{^6 \log 36 - ^6 \log 6 \sqrt 6 } \\ \frac {^6 \log 3^3. ^{3^{\frac {1}{2}}} \log 6^2 -^2^{2} \log 2^6}{^6 \log \frac {6^2}{\sqrt 6}  } \\ \frac {3.4-3}{^6 \log 6^{\frac {3}{2}} } \\ \frac {9}{\frac {3}{2}} =6$.
