Solution

simplify

(\frac{8}{7})^{- 2}

\frac{49}{64}

Decimal Notation

0.765625

Solution steps

(\frac{8}{7})^{- 2}

Apply exponent rule:

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

(\frac{8}{7})^{- 2} = \frac{1}{( \frac{8}{7} ) ^{2}}

= \frac{1}{( \frac{8}{7} ) ^{2}}

(\frac{8}{7})^{2} = \frac{64}{49}

= \frac{1}{\frac{64}{49}}

Apply the fraction rule:

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

= \frac{49}{64}

(\frac{2 x ^{4}}{3})^{3}

\frac{1}{6} - \frac{1}{12}

(x^{2} + 5 x)^{2} + 7 (x^{2} + 5 x) + 6

- 8 x^{2} = 0

\frac{\frac{2 π}{4}}{2}
