Step 17.1.4.2

Rewrite $4$ as $2^{2}$ .

$\frac{2 (25 \sqrt{3 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})} + 5 \sqrt{6 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})} + 15 \sqrt{6 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})} + 3 \sqrt{2^{2} \cdot 3 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})})}{483}$

Step 17.1.4.3

Add parentheses.

Step 17.1.4.4

Add parentheses.

$\frac{2 (25 \sqrt{3 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})} + 5 \sqrt{6 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})} + 15 \sqrt{6 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})} + 3 \sqrt{2^{2} \cdot (3 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2}))})}{483}$

Step 17.1.5

Pull terms out from under the radical.

$\frac{2 (25 \sqrt{3 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})} + 5 \sqrt{6 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})} + 15 \sqrt{6 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})} + 3 (2 \sqrt{3 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})}))}{483}$

Step 17.1.6

Multiply $2$ by $3$ .

$\frac{2 (25 \sqrt{3 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})} + 5 \sqrt{6 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})} + 15 \sqrt{6 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})} + 6 \sqrt{3 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})})}{483}$

Step 17.2

Add $25 \sqrt{3 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})}$ and $6 \sqrt{3 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})}$ .

$\frac{2 (31 \sqrt{3 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})} + 5 \sqrt{6 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})} + 15 \sqrt{6 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})})}{483}$

Step 17.3

Add $5 \sqrt{6 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})}$ and $15 \sqrt{6 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})}$ .

$\frac{2 (31 \sqrt{3 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})} + 20 \sqrt{6 \cdot (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})})}{483}$

$\frac{2 (31 \sqrt{3 (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})} + 20 \sqrt{6 (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})})}{483}$

Step 18

The result can be shown in multiple forms.

Exact Form:

$\frac{2 (31 \sqrt{3 (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})} + 20 \sqrt{6 (5 - 3 \sqrt{2}) (35 - 7 \sqrt{2})})}{483}$

Decimal Form:

$1.85385256 \dots$
