Question

Given that: $$\sqrt{2}=1.414,\sqrt{3}=1.732,\sqrt{5}=2.236\text{ and }\sqrt{7}=2.646,$$  find the square root of the following:

$$\frac{25}{50}$$ 

Answer 1

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

$$\sqrt{\frac{27}{50}}=\frac{3\sqrt{3}}{5\sqrt{2}}=\frac{3\times 1.732}{5\times 1.414}=0.735$$
