simplify (y^{2/3})^{-9}

Solution

simplify

(y^{\frac{2}{3}})^{- 9}

Solution

\frac{1}{y ^{6}}

Solution steps

(y^{\frac{2}{3}})^{- 9}

Apply exponent rule:

(a^{b})^{c} = a^{b c},

assuming

a \geq 0

= y^{\frac{2}{3} (- 9)}

\frac{2}{3} (- 9) = - 6

= y^{- 6}

Apply exponent rule:

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

y^{- 6} = \frac{1}{y ^{6}}

= \frac{1}{y ^{6}}

Popular Examples

- 6 < 3 (x - 3) \leq 9

9x(x+6)-(3x+1)^2=1

9 x (x + 6) - (3 x + 1)^{2} = 1

simplify ((4a^3b)/(6a^5b^{-2)})^3 simplify

(\frac{4 a ^{3} b}{6 a ^{5} b ^{- 2}})^{3}

factor 3k^4-48k^2 factor

3 k^{4} - 48 k^{2}

factor 125x^2-80 factor

125 x^{2} - 80
