Answer:- 1

Explanation:-

Solution:

\begin{aligned} 3 \sqrt{5} + \sqrt{125} = 17.88 \\ \Rightarrow 3 \sqrt{5} + \sqrt{25 \times 5} = 17.88 \\ \Rightarrow 3 \sqrt{5} + 5 \sqrt{5} = 17.88 \\ \Rightarrow 8 \sqrt{5} = 17.88 \\ \Rightarrow \sqrt{5} = 2.235 \\ ∴ \sqrt{80} + 6 \sqrt{5} = \sqrt{16 \times 5} + 6 \sqrt{5} \\ = 4 \sqrt{5} + 6 \sqrt{5} \\ = 10 \sqrt{5} = (10 \times 2.235) = 22.35 \end{aligned}

$\eqalign{ & 3\sqrt 5 + \sqrt {125} = 17.88 \cr & \Rightarrow 3\sqrt 5 + \sqrt {25 \times 5} = 17.88 \cr & \Rightarrow 3\sqrt 5 + 5\sqrt 5 = 17.88 \cr & \Rightarrow 8\sqrt 5 = 17.88 \cr & \Rightarrow \sqrt 5 = 2.235 \cr & \therefore \sqrt {80} + 6\sqrt 5 = \sqrt {16 \times 5} + 6\sqrt 5 \cr & = 4\sqrt 5 + 6\sqrt 5 \cr & = 10\sqrt 5 = \left( {10 \times 2.235} \right) = 22.35 \cr}$
