Step 2.1.26.4.2.1

Factor $2$ out of $2$ .

$x^{3} + 6 x^{2} \sqrt{3 x} + 45 x^{2} + 60 x \sqrt{3 x} + 135 x + 54 \sqrt{3 x} + 3^{\frac{2 \cdot 3}{2 (1)}}$

Step 2.1.26.4.2.2

Cancel the common factor.

$x^{3} + 6 x^{2} \sqrt{3 x} + 45 x^{2} + 60 x \sqrt{3 x} + 135 x + 54 \sqrt{3 x} + 3^{\frac{2 \cdot 3}{2 \cdot 1}}$

Step 2.1.26.4.2.3

Rewrite the expression.

$x^{3} + 6 x^{2} \sqrt{3 x} + 45 x^{2} + 60 x \sqrt{3 x} + 135 x + 54 \sqrt{3 x} + 3^{\frac{3}{1}}$

Step 2.1.26.4.2.4

Divide $3$ by $1$ .

$x^{3} + 6 x^{2} \sqrt{3 x} + 45 x^{2} + 60 x \sqrt{3 x} + 135 x + 54 \sqrt{3 x} + 3^{3}$

Step 2.1.27

Raise $3$ to the power of $3$ .

$x^{3} + 6 x^{2} \sqrt{3 x} + 45 x^{2} + 60 x \sqrt{3 x} + 135 x + 54 \sqrt{3 x} + 27$
