Question

Given that: 

\[\sqrt{2} = 1 . 414, \sqrt{3} = 1 . 732, \sqrt{5} = 2 . 236 \text{ and } \sqrt{7} = 2 . 646,\] 

\[\frac{256}{5}\]

Answer 1

From the given values, we can simplify the expressions in the following manner: 

\[ \sqrt{\frac{256}{5}} = \frac{16}{\sqrt{5}} = \frac{16}{2 . 236} = 7 . 155\]
