(\frac{7}{2})^{- 2}

Solution

\frac{4}{49}

+1

Decimal Notation

0.08163 \dots

Solution steps

(\frac{7}{2})^{- 2}

Apply exponent rule:

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

(\frac{7}{2})^{- 2} = \frac{1}{( \frac{7}{2} ) ^{2}}

= \frac{1}{( \frac{7}{2} ) ^{2}}

(\frac{7}{2})^{2} = \frac{49}{4}

= \frac{1}{\frac{49}{4}}

Apply the fraction rule:

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

= \frac{4}{49}
