Assume that $$\sqrt {13} $$ = 3.605(approximately) and $$\sqrt {130} $$  = 11.40(approximately) Find the value of: $$\sqrt {1.3}$$  $$+$$ $$\sqrt {1300}$$   $$+$$ $$\sqrt {0.013} $$

Solution (By Examveda Team)

According to the question,
$$\eqalign{ & \sqrt {1.3} + \sqrt {1300} + \sqrt {0.013} \cr & \Rightarrow \sqrt {\frac{{130}}{{100}} }+ \sqrt {1300} + \sqrt {\frac{{130}}{{10000}}} \cr & \Rightarrow \frac{{11.4}}{{10}} + 36.05 + \frac{{11.4}}{{100}} \cr & \Rightarrow 1.14 + 36.05 + 0.114 \cr & \Rightarrow 37.304 \cr} $$
