Step 1.1.1

Factor $8$ out of $48$ .

$\sqrt[3]{8 (6) x} - \sqrt[3]{162 x}$

Step 1.1.2

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

$\sqrt[3]{2^{3} \cdot 6 x} - \sqrt[3]{162 x}$

Step 1.1.3

Add parentheses.

$\sqrt[3]{2^{3} \cdot (6 x)} - \sqrt[3]{162 x}$

$\sqrt[3]{2^{3} \cdot (6 x)} - \sqrt[3]{162 x}$

Step 1.2

Pull terms out from under the radical.

$2 \sqrt[3]{6 x} - \sqrt[3]{162 x}$

Step 1.3

Rewrite $162 x$ as $3^{3} \cdot (6 x)$ .

Step 1.3.1

Factor $27$ out of $162$ .

$2 \sqrt[3]{6 x} - \sqrt[3]{27 (6) x}$

Step 1.3.2

Rewrite $27$ as $3^{3}$ .

$2 \sqrt[3]{6 x} - \sqrt[3]{3^{3} \cdot 6 x}$

Step 1.3.3

Add parentheses.

$2 \sqrt[3]{6 x} - \sqrt[3]{3^{3} \cdot (6 x)}$

$2 \sqrt[3]{6 x} - \sqrt[3]{3^{3} \cdot (6 x)}$

Step 1.4

Pull terms out from under the radical.

$2 \sqrt[3]{6 x} - (3 \sqrt[3]{6 x})$

Step 1.5

Multiply $3$ by $- 1$ .

$2 \sqrt[3]{6 x} - 3 \sqrt[3]{6 x}$

$2 \sqrt[3]{6 x} - 3 \sqrt[3]{6 x}$

Step 2

Subtract $3 \sqrt[3]{6 x}$ from $2 \sqrt[3]{6 x}$ .

$- \sqrt[3]{6 x}$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
