How do you simplify (z ^ { - 4} \cdot x ^ { \frac { 3} { 5} } ) ^ { \frac { 1} { 3} }(z4x35)13?

z^(-4/3)*x^(1/5)=root(5)x/(zroot(3)(z))z43x15=5xz3z

Explanation:

Since (a^b)^c=a^(bc)(ab)c=abc, you would get:

(z^-4*x^(3/5))^(1/3)=z^(-4/3)*x^(1/5)(z4x35)13=z43x15

and, since a^(m/n)=root(n)(a^m)amn=nam, you could write the equivalent expression:

root(5)x/root(3)(z^4)=root(5)x/(zroot(3)(z))5x3z4=5xz3z
