\({1x}^{-1} = 1\left ( \frac{1}{x}\right ) = \frac{1}{x}\)
\({2x}^{-2} = 2\left ( \frac{1}{{x}^{2}} \right ) = \frac{2}{{x}^{2}}\)
\(\frac{2}{3}{x}^{-2} = \frac{2}{3}\left ( \frac{1}{{x}^{2}} \right ) = \frac{2}{3{x}^{2}}\)
\(\times {10}^{-1} = \times \frac{1}{{10}^{1}}\)which is the same as dividing by 10
\(35\times{10}^{-2}\) \(=\) \(35\times\frac{1}{{10}^{2}}\) \(=\) \(35\times\frac{1}{100}\) \(=\) \(\frac{35}{100} = 0.35\)
