The square root of \[\frac{36}{5}\] correct up to two decimal places is _____.

A) 2.68

B) 2.69

C)        2.67

D)        2.66

Correct Answer: A

Solution :

Since we have to find the square root of \[\frac{36}{5}\] correct up to two decimal places. So, we have to find its square root up to three decimal places. \[\therefore \frac{36}{5}=7.200000\] Now,

	2.683
2	\[\begin{align} & \,\,\,\,\overline{7}.\overline{200000} \\ & -\,4 \\ \end{align}\]
46	320 -276
528	4400 - 4224
5363	17600 - 16089
	1511

\[\therefore \sqrt{\frac{36}{5}}=2.683\] (upto 3 decimal places) \[\Rightarrow \sqrt{\frac{36}{5}}=2.68\]
