$x^{\frac{20}{7}} y^{- \frac{8}{7}} z^{- \frac{10}{7}}$ $x^(20/7)y^(-8/7)z^(-10/7)$

or $\frac{x^{\frac{20}{7}}}{y^{\frac{8}{7}} z^{\frac{10}{7}}}$ $[x^(20/7)]/[y^(8/7)z^(10/7)]$

multiply the powers together

$x^{\frac{20}{7}} y^{- \frac{8}{7}} z^{- \frac{10}{7}}$ $x^(20/7)y^(-8/7)z^(-10/7)$

How do you simplify (x^-10y^4 z^5)^-( 2/7)(x−10y4z5)−(27) (x^-10y^4 z^5)^-( 2/7)?
