Solution

1). x^-4 y^10 / 3z^4 . (xz)^3 /y^3 . (y^-2 z^3)^4 / (x^-2)^-2

things to remember

the first step used is (ab)^n = a^n . b^n

so here(xy)^3 = x^3 . y^3

in the step property used is

(x^m)^n = x^mn

so (y^-2 z^3)^4 / (x^-2)^-2 = y^-8 . z^12 / x^4

in all the remaining steps collection same terms together

x^m . x^-n = x^(m-n)

x^m . x^n = x^(m+n)

2).
