simplify ((9^3)/(6^3))^{-1/3}

simplify

(\frac{9 ^{3}}{6 ^{3}})^{- \frac{1}{3}}

\frac{2}{3}

Decimal Notation

0.66666 \dots

Solution steps

(\frac{9 ^{3}}{6 ^{3}})^{- \frac{1}{3}}

Apply exponent rule:

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

(\frac{9 ^{3}}{6 ^{3}})^{- \frac{1}{3}} = \frac{1}{( \frac{9 ^{3}}{6 ^{3}} ) ^{\frac{1}{3}}}

= \frac{1}{( \frac{9 ^{3}}{6 ^{3}} ) ^{\frac{1}{3}}}

(\frac{9 ^{3}}{6 ^{3}})^{\frac{1}{3}} = \frac{3}{2}

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

Apply the fraction rule:

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

= \frac{2}{3}

a^{3} - a^{2} x + a x^{2}

4 x^{2} - 28 x + 49 \leq 0

- 6 x - 2 (x - 5) = 4

12 5^{\frac{1}{3}} + 1 6^{\frac{1}{2}}

- 2 < 2 d - 2 \leq 6
