# How do you simplify ((3x^4)/y^6)^5 and write it using only positive exponents?

$\frac{243 {x}^{20}}{y} ^ 30$
We can rewrite ${\left(\frac{3 {x}^{4}}{y} ^ 6\right)}^{5}$ as
$\frac{{3}^{5} {\left({x}^{4}\right)}^{5}}{{y}^{6}} ^ 5 = \frac{{3}^{5} {x}^{4 \cdot 5}}{y} ^ \left(6 \cdot 5\right) = \frac{243 {x}^{20}}{y} ^ 30$
