Answer 2

Hey friend,
Here is the answer you were looking for:
$1) \\ \sqrt{72} + \sqrt{48} \\ \\ splitting \\ \\ = \sqrt{2 \times 2 \times 2 \times 3 \times 3} + \sqrt{2 \times 2 \times 2 \times 2 \times 3} \\ \\ = 2 \times 3 \sqrt{2} + 2 \times 2 \sqrt{3} \\ \\ = 6 \sqrt{2} + 4 \sqrt{3} \\ \\ given \\ \sqrt{2} = 1.414 \\ \sqrt{3} = 1.732 \\ \\ = 6 \sqrt{2} + 4 \sqrt{3} \\ \\ = 6 \times 1.414 + 4 \times 1.732 \\ \\ = 8.484 + 6.928 \\ \\ = 15.412 \\ \\ 2) \\ \sqrt{ \frac{125}{64} } \\ \\ splitting \\ \\ \sqrt{ \frac{5 \times 5 \times 5}{2 \times 2 \times 2 \times 2 \times 2 \times 2} } \\ \\ = \frac{5}{2 \times 2 \times 2} \sqrt{5} \\ \\ = \frac{5}{8} \sqrt{5} \\ \\ given \\ \sqrt{5} = 2.236 \\ \\ = \frac{5}{8} \times 2.236 \\ \\ on \: cancelling \: we \: get \\ \\ = \frac{5}{2} \times 0.559 \\ \\ = \frac{2.795}{2} \\ \\ = 1.3975 \\ \\ = 1.397$


Hope this helps!!!
