Solution

\frac{25}{4}

+1

Decimal Notation

6.25

Solution steps

(\frac{- 2}{5})^{- 2}

Apply exponent rule:

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

(\frac{- 2}{5})^{- 2} = \frac{1}{( \frac{- 2}{5} ) ^{2}}

= \frac{1}{( \frac{- 2}{5} ) ^{2}}

(\frac{- 2}{5})^{2} = \frac{4}{25}

= \frac{1}{\frac{4}{25}}

\frac{1}{\frac{b}{c}} = \frac{c}{b}

= \frac{25}{4}
