$$\mathrm{Apply\:exponent\:rule}:\quad \left(a\cdot \:b\right)^n=a^nb^n$$

$$\left(x^4y^7\right)^{\frac{2}{3}}=\left(x^4\right)^{\frac{2}{3}}\left(y^7\right)^{\frac{2}{3}}$$

$$=\left(x^4\right)^{\frac{2}{3}}\left(y^7\right)^{\frac{2}{3}}$$

Simplify:

=$$x^{\frac{8}{3}}\left(y^7\right)^{\frac{2}{3}}$$

Simplify:

$$x^{\frac{8}{3}}y^{\frac{14}{3}}$$

$$x^{\frac{8}{3}}y^{\frac{14}{3}}$$
