$5 \sqrt{3 a} + \sqrt{12 a} + \sqrt{27 a}$

Step 1

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{3 a}$ as ${(3 a)}^{\frac{1}{2}}$ .

$5 {(3 a)}^{\frac{1}{2}} + \sqrt{12 a} + \sqrt{27 a}$

Step 2

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{12 a}$ as ${(12 a)}^{\frac{1}{2}}$ .

$5 {(3 a)}^{\frac{1}{2}} + {(12 a)}^{\frac{1}{2}} + \sqrt{27 a}$

Step 3

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{27 a}$ as ${(27 a)}^{\frac{1}{2}}$ .

$5 {(3 a)}^{\frac{1}{2}} + {(12 a)}^{\frac{1}{2}} + {(27 a)}^{\frac{1}{2}}$

Step 4

Apply the product rule to $3 a$ .

$5 (3^{\frac{1}{2}} a^{\frac{1}{2}}) + {(12 a)}^{\frac{1}{2}} + {(27 a)}^{\frac{1}{2}}$

Step 5

Remove parentheses.

$5 \cdot 3^{\frac{1}{2}} a^{\frac{1}{2}} + {(12 a)}^{\frac{1}{2}} + {(27 a)}^{\frac{1}{2}}$

Step 6

Apply the product rule to $12 a$ .

$5 \cdot 3^{\frac{1}{2}} a^{\frac{1}{2}} + 12^{\frac{1}{2}} a^{\frac{1}{2}} + {(27 a)}^{\frac{1}{2}}$

Step 7

Apply the product rule to $27 a$ .

$5 \cdot 3^{\frac{1}{2}} a^{\frac{1}{2}} + 12^{\frac{1}{2}} a^{\frac{1}{2}} + 27^{\frac{1}{2}} a^{\frac{1}{2}}$

Step 8

Factor $a^{\frac{1}{2}}$ out of $5 \cdot 3^{\frac{1}{2}} a^{\frac{1}{2}} + 12^{\frac{1}{2}} a^{\frac{1}{2}} + 27^{\frac{1}{2}} a^{\frac{1}{2}}$ .

Step 8.2

Factor $a^{\frac{1}{2}}$ out of $12^{\frac{1}{2}} a^{\frac{1}{2}}$ .

$a^{\frac{1}{2}} (5 \cdot 3^{\frac{1}{2}}) + a^{\frac{1}{2}} \cdot 12^{\frac{1}{2}} + 27^{\frac{1}{2}} a^{\frac{1}{2}}$

Step 8.3

Factor $a^{\frac{1}{2}}$ out of $27^{\frac{1}{2}} a^{\frac{1}{2}}$ .

$a^{\frac{1}{2}} (5 \cdot 3^{\frac{1}{2}}) + a^{\frac{1}{2}} \cdot 12^{\frac{1}{2}} + a^{\frac{1}{2}} \cdot 27^{\frac{1}{2}}$

Step 8.4

Factor $a^{\frac{1}{2}}$ out of $a^{\frac{1}{2}} (5 \cdot 3^{\frac{1}{2}}) + a^{\frac{1}{2}} \cdot 12^{\frac{1}{2}}$ .

$a^{\frac{1}{2}} (5 \cdot 3^{\frac{1}{2}} + 12^{\frac{1}{2}}) + a^{\frac{1}{2}} \cdot 27^{\frac{1}{2}}$

Step 8.5

Factor $a^{\frac{1}{2}}$ out of $a^{\frac{1}{2}} (5 \cdot 3^{\frac{1}{2}} + 12^{\frac{1}{2}}) + a^{\frac{1}{2}} \cdot 27^{\frac{1}{2}}$ .

$a^{\frac{1}{2}} (5 \cdot 3^{\frac{1}{2}} + 12^{\frac{1}{2}} + 27^{\frac{1}{2}})$
