Step 1.1.1

Factor $64$ out of $192$ .

$- 3 \sqrt[6]{3} - 2 \sqrt[6]{64 (3)} - \sqrt[6]{320}$

Step 1.1.2

Rewrite $64$ as $2^{6}$ .

$- 3 \sqrt[6]{3} - 2 \sqrt[6]{2^{6} \cdot 3} - \sqrt[6]{320}$

Step 1.2

Pull terms out from under the radical.

$- 3 \sqrt[6]{3} - 2 (| 2 | \sqrt[6]{3}) - \sqrt[6]{320}$

Step 1.3

The absolute value is the distance between a number and zero. The distance between $0$ and $2$ is $2$ .

$- 3 \sqrt[6]{3} - 2 (2 \sqrt[6]{3}) - \sqrt[6]{320}$

Step 1.4

Multiply $2$ by $- 2$ .

$- 3 \sqrt[6]{3} - 4 \sqrt[6]{3} - \sqrt[6]{320}$

Step 1.5

Rewrite $320$ as $2^{6} \cdot 5$ .

Step 1.5.1

Factor $64$ out of $320$ .

$- 3 \sqrt[6]{3} - 4 \sqrt[6]{3} - \sqrt[6]{64 (5)}$

Step 1.5.2

Rewrite $64$ as $2^{6}$ .

$- 3 \sqrt[6]{3} - 4 \sqrt[6]{3} - \sqrt[6]{2^{6} \cdot 5}$

Step 1.6

Pull terms out from under the radical.

$- 3 \sqrt[6]{3} - 4 \sqrt[6]{3} - (| 2 | \sqrt[6]{5})$

Step 1.7

The absolute value is the distance between a number and zero. The distance between $0$ and $2$ is $2$ .

$- 3 \sqrt[6]{3} - 4 \sqrt[6]{3} - (2 \sqrt[6]{5})$

Step 1.8

Multiply $2$ by $- 1$ .

$- 3 \sqrt[6]{3} - 4 \sqrt[6]{3} - 2 \sqrt[6]{5}$

Step 2

Subtract $4 \sqrt[6]{3}$ from $- 3 \sqrt[6]{3}$ .

$- 7 \sqrt[6]{3} - 2 \sqrt[6]{5}$

Step 3

The result can be shown in multiple forms.

Exact Form:

$- 7 \sqrt[6]{3} - 2 \sqrt[6]{5}$
