Solution

simplify

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

- \frac{1}{8}

Decimal Notation

- 0.125

Solution steps

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

Apply exponent rule:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

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

(- 1)^{3} = - 1

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

2^{3} = 8

= \frac{- 1}{8}

Apply the fraction rule:

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

= - \frac{1}{8}

\frac{x - 6}{x ^{2} - 36}

7 + (- 1)

(a + b + c)^{4}

(\frac{3}{5} + \frac{5}{2} i)^{2}

(a^{2} + ab + b^{2}) (a - b)
