Step 1.1

Rewrite $9$ as $3^{2}$ .

$\frac{4 \sqrt{10} + \sqrt{11} + \sqrt{110} + 13}{\sqrt{3^{2}} + \sqrt{10} + \sqrt{11}}$

Step 1.2

Pull terms out from under the radical, assuming positive real numbers.

$\frac{4 \sqrt{10} + \sqrt{11} + \sqrt{110} + 13}{3 + \sqrt{10} + \sqrt{11}}$

Step 2

Multiply $\frac{4 \sqrt{10} + \sqrt{11} + \sqrt{110} + 13}{3 + \sqrt{10} + \sqrt{11}}$ by $\frac{3 + \sqrt{10} - \sqrt{11}}{3 + \sqrt{10} - \sqrt{11}}$ .

$\frac{4 \sqrt{10} + \sqrt{11} + \sqrt{110} + 13}{3 + \sqrt{10} + \sqrt{11}} \cdot \frac{3 + \sqrt{10} - \sqrt{11}}{3 + \sqrt{10} - \sqrt{11}}$

Step 3

Multiply $\frac{4 \sqrt{10} + \sqrt{11} + \sqrt{110} + 13}{3 + \sqrt{10} + \sqrt{11}}$ by $\frac{3 + \sqrt{10} - \sqrt{11}}{3 + \sqrt{10} - \sqrt{11}}$ .

$\frac{(4 \sqrt{10} + \sqrt{11} + \sqrt{110} + 13) (3 + \sqrt{10} - \sqrt{11})}{(3 + \sqrt{10} + \sqrt{11}) (3 + \sqrt{10} - \sqrt{11})}$

Step 4

Expand the denominator using the FOIL method.

$\frac{(4 \sqrt{10} + \sqrt{11} + \sqrt{110} + 13) (3 + \sqrt{10} - \sqrt{11})}{9 + 3 \sqrt{10} - 3 \sqrt{11} + \sqrt{10} \cdot 3 + {\sqrt{10}}^{2} - \sqrt{110} + \sqrt{11} \cdot 3 + \sqrt{110} - {\sqrt{11}}^{2}}$

Step 5

Simplify.

$\frac{(4 \sqrt{10} + \sqrt{11} + \sqrt{110} + 13) (3 + \sqrt{10} - \sqrt{11})}{8 + 6 \sqrt{10}}$

Step 6

Multiply $\frac{(4 \sqrt{10} + \sqrt{11} + \sqrt{110} + 13) (3 + \sqrt{10} - \sqrt{11})}{8 + 6 \sqrt{10}}$ by $\frac{8 - 6 \sqrt{10}}{8 - 6 \sqrt{10}}$ .

$\frac{(4 \sqrt{10} + \sqrt{11} + \sqrt{110} + 13) (3 + \sqrt{10} - \sqrt{11})}{8 + 6 \sqrt{10}} \cdot \frac{8 - 6 \sqrt{10}}{8 - 6 \sqrt{10}}$

Step 7

Multiply $\frac{(4 \sqrt{10} + \sqrt{11} + \sqrt{110} + 13) (3 + \sqrt{10} - \sqrt{11})}{8 + 6 \sqrt{10}}$ by $\frac{8 - 6 \sqrt{10}}{8 - 6 \sqrt{10}}$ .

$\frac{(4 \sqrt{10} + \sqrt{11} + \sqrt{110} + 13) (3 + \sqrt{10} - \sqrt{11}) (8 - 6 \sqrt{10})}{(8 + 6 \sqrt{10}) (8 - 6 \sqrt{10})}$

Step 8

Expand the denominator using the FOIL method.

$\frac{(4 \sqrt{10} + \sqrt{11} + \sqrt{110} + 13) (3 + \sqrt{10} - \sqrt{11}) (8 - 6 \sqrt{10})}{64 - 48 \sqrt{10} + 48 \sqrt{10} - 36 {\sqrt{10}}^{2}}$

Step 9

Simplify.

$\frac{(4 \sqrt{10} + \sqrt{11} + \sqrt{110} + 13) (3 + \sqrt{10} - \sqrt{11}) (8 - 6 \sqrt{10})}{- 296}$
