0. 5^{- 3}

8

Solution steps

0. 5^{- 3}

Apply exponent rule:

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

0. 5^{- 3} = \frac{1}{0. 5 ^{3}}

= \frac{1}{0. 5 ^{3}}

0. 5^{3} = 0.125

= \frac{1}{0.125}

Divide the numbers:

\frac{1}{0.125} = 8

= 8

\frac{1}{10} \div \frac{1}{4}

8^{1.5}

\frac{1}{x} + \frac{3}{y} - \frac{y}{x ^{2}}

π \times 8^{2}

2 x^{7} y^{3} \cdot 7 x^{5} y^{4}
