Work Step by Step

$$\frac{72x^{\frac{3}{4}}}{9x^{\frac{1}{3}}}$$ When two rational expressions with the same base are divided, subtract the exponents. $$=(\frac{72}{9})(x^{(\frac{3}{4} - \frac{1}{3})})$$ When subtracting fractions, you need a common denominator, in this case, 12: $$=8x^{(\frac{9}{12} - \frac{4}{12})}$$ $$=8x^{\frac{5}{12}}$$
