Given that $$\sqrt {13} $$ = 3.6 and $$\sqrt {130} $$ = 11.4, then the value of $$\sqrt {13} $$ + $$\sqrt {1300} $$ + $$\sqrt {0.013} $$ is equal to = ?
Answer & Solution
Correct Answer:
Option
C
$$\eqalign{
& {\text{According to question}} \cr
& \sqrt {13} {\text{ + }}\sqrt {1300} {\text{ + }}\sqrt {0.013} \cr
& = 3.6 + 10\sqrt {13} + \sqrt {\frac{{130}}{{10000}}} \cr
& = 3.6 + 10 \times 3.6 + \frac{{11.4}}{{100}} \cr
& = 39.714 \cr} $$
