Step 2

Pull terms out from under the radical.

$y^{4} \sqrt[3]{y} \sqrt[3]{16 y^{14}}$

Step 3

Rewrite $16 y^{14}$ as ${(2 y^{4})}^{3} \cdot (2 y^{2})$ .

Factor $8$ out of $16$ .

$y^{4} \sqrt[3]{y} \sqrt[3]{8 (2) y^{14}}$

Rewrite $8$ as $2^{3}$ .

$y^{4} \sqrt[3]{y} \sqrt[3]{2^{3} \cdot 2 y^{14}}$

Factor out $y^{12}$ .

$y^{4} \sqrt[3]{y} \sqrt[3]{2^{3} \cdot 2 (y^{12} y^{2})}$

Rewrite $y^{12}$ as ${(y^{4})}^{3}$ .

$y^{4} \sqrt[3]{y} \sqrt[3]{2^{3} \cdot 2 ({(y^{4})}^{3} y^{2})}$

Move $2$ .

$y^{4} \sqrt[3]{y} \sqrt[3]{2^{3} {(y^{4})}^{3} \cdot 2 y^{2}}$

Rewrite $2^{3} {(y^{4})}^{3}$ as ${(2 y^{4})}^{3}$ .

$y^{4} \sqrt[3]{y} \sqrt[3]{{(2 y^{4})}^{3} \cdot 2 y^{2}}$

Add parentheses.

$y^{4} \sqrt[3]{y} \sqrt[3]{{(2 y^{4})}^{3} \cdot (2 y^{2})}$

Step 4

Pull terms out from under the radical.

$y^{4} \sqrt[3]{y} (2 y^{4} \sqrt[3]{2 y^{2}})$

Step 5

Rewrite using the commutative property of multiplication.

$2 y^{4} \sqrt[3]{y} (y^{4} \sqrt[3]{2 y^{2}})$

Step 6

Multiply $y^{4}$ by $y^{4}$ by adding the exponents.

Move $y^{4}$ .

$2 (y^{4} y^{4}) \sqrt[3]{y} \sqrt[3]{2 y^{2}}$

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

$2 y^{4 + 4} \sqrt[3]{y} \sqrt[3]{2 y^{2}}$

Add $4$ and $4$ .

$2 y^{8} \sqrt[3]{y} \sqrt[3]{2 y^{2}}$

Step 7

Multiply $2 y^{8} \sqrt[3]{y} \sqrt[3]{2 y^{2}}$ .

Combine using the product rule for radicals.

$2 y^{8} \sqrt[3]{2 y^{2} y}$

Raise $y$ to the power of $1$ .

$2 y^{8} \sqrt[3]{2 (y^{1} y^{2})}$

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

$2 y^{8} \sqrt[3]{2 y^{1 + 2}}$

Add $1$ and $2$ .

$2 y^{8} \sqrt[3]{2 y^{3}}$

Step 8

Reorder $2$ and $y^{3}$ .

$2 y^{8} \sqrt[3]{y^{3} \cdot 2}$

Step 9

Pull terms out from under the radical.

$2 y^{8} (y \sqrt[3]{2})$

Step 10

Multiply $y^{8}$ by $y$ by adding the exponents.

Move $y$ .

$2 (y \cdot y^{8}) \sqrt[3]{2}$

Multiply $y$ by $y^{8}$ .

Raise $y$ to the power of $1$ .

$2 (y^{1} y^{8}) \sqrt[3]{2}$

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

$2 y^{1 + 8} \sqrt[3]{2}$

Add $1$ and $8$ .

$2 y^{9} \sqrt[3]{2}$
