Fractional Exponents

Write the fractional exponents in radical form.

1. $4^{\frac{2}{3}}$
2. $a^{\frac{4}{5}}$
3. $x^{\frac{1}{2}}y^{\frac{3}{4}}$

Simplify fractional exponents.

4. $(4^{\frac{2}{3}})(4^{\frac{1}{3}})$
5. $(2^{\frac{4}{5}})^{\frac{1}{2}}$
6. $1^{\frac{1}{2}}3^{\frac{3}{4}}$
7. $(x^{\frac{2}{5}})^{\frac{2}{3}}$
8. $(3^2)^{\frac{2}{3}}$
9. $\dfrac{x^{\frac{1}{4}}}{x^{\frac{1}{2}}}$
10. $\dfrac{x^{\frac{1}{8}}y^{\frac{2}{3}}}{x^{\frac{1}{4}}y^{\frac{1}{3}}}$
11. $\dfrac{2^{\frac{5}{6}}}{2^{\frac{2}{3}}}$
12. $\dfrac{3^{\frac{2}{3}}}{3^{\frac{4}{3}}}$
