+1

Decimal Notation

Solution steps

(\frac{9}{49})^{\frac{- 1}{2}}

Apply exponent rule:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

= \frac{9 ^{\frac{- 1}{2}}}{4 9 ^{\frac{- 1}{2}}}

9^{\frac{- 1}{2}} = \frac{1}{3}

= \frac{\frac{1}{3}}{4 9 ^{\frac{- 1}{2}}}

4 9^{\frac{- 1}{2}} = \frac{1}{7}

= \frac{\frac{1}{3}}{\frac{1}{7}}

\frac{\frac{1}{3}}{\frac{1}{7}} = \frac{7}{3}

= \frac{7}{3}
