Question

Evaluate:

$\frac{{\left(\frac{-3}{5}\right)}^3\times {\left(\frac{9}{25}\right)}^2\times {\left(\frac{-18}{125}\right)}^0}{\frac{-27}{125}\times \left(\frac{-3}{5}\right)}$.

Answer 1

$\frac{{\left(\frac{-3}{5}\right)}^3\times {\left(\frac{9}{25}\right)}^2\times {\left(\frac{-18}{125}\right)}^0}{\left(\frac{-27}{125}\right)\times \frac{-3}{5}}=\frac{{\left(\frac{-3}{5}\right)}^3\times {\left(\frac{-3}{5}\right)}^4\times 1}{{\left(\frac{-3}{5}\right)}^3\times \frac{-3}{5}}={\left(\frac{-3}{5}\right)}^3=\frac{-27}{125}$
