$x^{\frac{2}{3}} + \frac{1}{x^{\frac{2}{3}}}$

Step 1

To write $x^{\frac{2}{3}}$ as a fraction with a common denominator, multiply by $\frac{x^{\frac{2}{3}}}{x^{\frac{2}{3}}}$ .

$\frac{x^{\frac{2}{3}} x^{\frac{2}{3}}}{x^{\frac{2}{3}}} + \frac{1}{x^{\frac{2}{3}}}$

Step 2

Combine the numerators over the common denominator.

$\frac{x^{\frac{2}{3}} x^{\frac{2}{3}} + 1}{x^{\frac{2}{3}}}$

Step 3
