Step 1.1

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{y}$ as $y^{\frac{1}{2}}$ .

$y^{\frac{1}{2}} \sqrt[3]{y}$

Step 1.2

Rewrite $y^{\frac{1}{2}}$ as $y^{\frac{3}{6}}$ .

$y^{\frac{3}{6}} \sqrt[3]{y}$

Step 1.3

Rewrite $y^{\frac{3}{6}}$ as $\sqrt[6]{y^{3}}$ .

$\sqrt[6]{y^{3}} \sqrt[3]{y}$

Step 1.4

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt[3]{y}$ as $y^{\frac{1}{3}}$ .

$\sqrt[6]{y^{3}} y^{\frac{1}{3}}$

Step 1.5

Rewrite $y^{\frac{1}{3}}$ as $y^{\frac{2}{6}}$ .

$\sqrt[6]{y^{3}} y^{\frac{2}{6}}$

Step 1.6

Rewrite $y^{\frac{2}{6}}$ as $\sqrt[6]{y^{2}}$ .

$\sqrt[6]{y^{3}} \sqrt[6]{y^{2}}$

Step 2

Combine using the product rule for radicals.

$\sqrt[6]{y^{3} y^{2}}$

Step 3

Multiply $y^{3}$ by $y^{2}$ by adding the exponents.

Step 3.1

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$\sqrt[6]{y^{3 + 2}}$

Step 3.2

Add $3$ and $2$ .

$\sqrt[6]{y^{5}}$
