Question

$\sqrt{1+\frac{27}{169}}=1+\frac{x}{13}$ആയാൽ x എത്ര?

• A. 1
• B. 2
• C. 27
• D. 14

Answer 1

Answer:

A. 1

$\sqrt{1+\frac{27}{169}}=1+\frac{x}{13}$

$\sqrt{\frac{169+27}{169}}=\frac{13+x}{13}$

$\sqrt{\frac{196}{169}}=\frac{13+x}{13}$

$\implies\frac{14}{13}=\frac{13+x}{13}$

$14=13+x,\implies x =1$
