simplify (7/21)^{-3}

Solution

simplify

(\frac{7}{21})^{- 3}

Solution

27

Solution steps

(\frac{7}{21})^{- 3}

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

(\frac{7}{21})^{- 3} = \frac{1}{( \frac{7}{21} ) ^{3}}

= \frac{1}{( \frac{7}{21} ) ^{3}}

(\frac{7}{21})^{3} = \frac{1}{27}

= \frac{1}{\frac{1}{27}}

\frac{1}{\frac{1}{27}} = 27

= 27
