simplify-2(3/2)^{-2}

Solution

simplify

- 2 (\frac{3}{2})^{- 2}

Solution

- \frac{8}{9}

+1

Decimal Notation

- 0.88888 \dots

Solution steps

- 2 (\frac{3}{2})^{- 2}

Apply exponent rule:

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

(\frac{3}{2})^{- 2} = \frac{1}{( \frac{3}{2} ) ^{2}}

= - 2 \cdot \frac{1}{( \frac{3}{2} ) ^{2}}

(\frac{3}{2})^{2} = \frac{9}{4}

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

Apply the fraction rule:

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

= - 2 \cdot \frac{4}{9}

- 2 \cdot \frac{4}{9} = - \frac{8}{9}

= - \frac{8}{9}
