Answer 2

Hi friend, Harish here.

Here is your answer:

To find,

The value of $\sqrt{ \frac{0.324}{72.9} }$

Solution:

We know that,

√(324) = 18 ; √100 = 10  & √(729) = 27 .

Then,

⇒ $\sqrt{ \frac{0.324}{72.9} } = \sqrt{ \frac{0.324 \times 1000}{72.9\times 1000} }$

⇒ $\sqrt{ \frac{324}{729\times 100} } = \sqrt{\frac{18^{2}}{27^{2}\times 10^{2}}} = \frac{18}{27\times 10} = \frac{1}{3\times 5} = \frac{1}{15}$

$\bold{Therefore\ the \ answer \ is\ \boxed{ \frac{1}{15}}.}$
