Step 1.1

Factor $27$ out of $27 x$ .

$\sqrt[3]{27 (x) - 81} - 5$

Step 1.2

Factor $27$ out of $- 81$ .

$\sqrt[3]{27 x + 27 \cdot - 3} - 5$

Step 1.3

Factor $27$ out of $27 x + 27 \cdot - 3$ .

$\sqrt[3]{27 (x - 3)} - 5$

$\sqrt[3]{27 (x - 3)} - 5$

Step 2

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

$\sqrt[3]{3^{3} (x - 3)} - 5$

Step 3

Pull terms out from under the radical.

$3 \sqrt[3]{x - 3} - 5$

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