Question

Simplifyx^-1 X (y^-8 X z^5)^3------------------------------x^-4 X y^-3 X z^6

Answer 1

Given:

`(x^(-1)\left(y^(-8)z^5\right)^3)/(x^(-4)y^(-3)z^6)`

Simplify:

`(x^(-1)y^(-24)z^(15))/(x^(-4)y^(-3)z^6)`

And:

`x^(-1-(-4))y^(-24-(-3))z^(15-6)=x^3y^(-21)z^9`

Re order:

`(x^3z^9)/(y^(21))`

Answer:

`(x^(3)z^(9))/(y^(21))`
