# Solve this: Q. Convert into power notation a. $\frac{-27}{125}$ b. $\frac{49}{81}$

Dear student,
(a) $\frac{-27}{125}=\frac{-3×-3×-3}{5×5×5}=\frac{\left(-3{\right)}^{3}}{{5}^{3}}$=$\left(\frac{-3}{5}{\right)}^{3}$, Which is the required power notation.
(b)$\frac{49}{81}=\frac{7×7}{9×9}=\frac{{7}^{2}}{{9}^{2}}$=$\left(\frac{7}{9}{\right)}^{2}$,Which is the required power notation.
Regards
