The value of $\frac{\sqrt{0.6912} + \sqrt{0.5292}}{\sqrt{0.6912} - \sqrt{0.5292}}$ is:
Answer & explanation
Correct answer: option 3
$\frac{\sqrt{0.6912} + \sqrt{0.5292}}{\sqrt{0.6912} - \sqrt{0.5292}}$
we can eliminate the LCM form the numerator and denominator because the places are the same after decimal.
= $\frac{\sqrt{6912} + \sqrt{5292}}{\sqrt{6912} - \sqrt{5292}}$
Take 12 as common from numerator and denominator.
= $\frac{\sqrt{576} + \sqrt{441}}{\sqrt{576} - \sqrt{441}}$
= $\frac{24 + 21}{24 - 21}$
= $\frac{45}{3}$ = 15
