Power functions and first sketches practice question 13

Both sides are powers of $x$, one in disguise. How can you gather everything into a single power of $x$ equal to a number?

Write $\sqrt{x}$ as $x^{1/2}$, then divide both sides by $x^{1/2}$ (allowed, since $x > 0$).

You should reach $x^{3/2} = 4$. Raise both sides to the power $\tfrac{2}{3}$.
