Answer 2

Step-by-step explanation:

Question :

If $\bold {\sqrt{1+\frac{x}{144} }=\frac{13}{12} } }$, then x is equal to ?

Solution :

$\rightarrowtail$ $\bold{\sqrt{1+\frac{x}{144}}=\frac{13}{12} } }$

Squaring on both sides, we get :

$\rightarrowtail \bold{(\sqrt{1+\frac{x}{144})^2 }=(\frac{13}{12}) ^2 }$

$\rightarrowtail \bold{1+\frac{x}{144}=\frac{169}{144} }$

Transposing 1, we get :

$\rightarrowtail \bold{\frac{x}{144}=\frac{169}{144}-1 }$

Taking L.C.M, we get :

$\rightarrowtail \bold{\frac{x}{144}=\frac{169-144}{144} }$

$\rightarrowtail \bold{\frac{x}{144}=\frac{25}{144} }$

Cross multiplying, we get :

$\rightarrowtail \bold{x\times144=25\times144}$

$\rightarrowtail \bold{144x=3600}$

$\rightarrowtail \bold{x=\frac{3600}{144} = 25}$

∴ Value of x is 25.
