Question

Ex cause me guys !

How can I simplify this x^2(y^2*z^3)^-2/y^3(xz^-3)^2 .

Answer 1

(x^2y^-4z^-6)/(y^3x^2z^-6)
subtract exponents of like variables:
x^(2-2) y^(-4-3) z^(-6-(-6)

x^0 y^(-7) z^(-6+6)

1* y^(-7) z^(0)

y^(-7) * 1

1/y^7

Answer 2

Could you please explain than for me ? Because I am still confused.
