Work Step by Step

$$\frac{20x^{\frac{1}{2}}}{5x^\frac{1}{4}}$$ When two rational expressions with the same base are divided, subtract the exponents. $$=(\frac{20}{5})(x^{(\frac{1}{2} - \frac{1}{4})})$$ When subtracting fractions, you need a common denominator, in this case, 4: $$=4x^{(\frac{2}{4} - \frac{1}{4})}$$ $$=4x^{\frac{1}{4}}$$
