# How do you simplify (3xz^5)^3 and write it using only positive exponents?

Distribute the exponent to each of the terms. Remember ${x}^{{a}^{b}} = {x}^{a b}$
Since everything is being multiplied we can rewrite the expression as ${3}^{3} {x}^{3} {z}^{{5}^{3}}$, which simplifies to $27 {x}^{3} {z}^{15}$
