Answer 2

Therefore the Answer is $0.94868$

Step-by-step explanation:

Given;

$\sqrt{0.9} =?$

We can also write,

$\sqrt{\frac{9}{10} }$

$=\sqrt{\frac{9\times10}{10\times10} }$   (multiply on both side numerator and denominator)

$=\sqrt{\frac{90}{100} }$

$=\frac{1}{10} \sqrt{90}$  (∵$\sqrt{100} =10$ )

$=\frac{9.4868}{10}$   (∵$\sqrt{90} =9.4868$)

$=0.94868$

So the Answer is $0.94868$
