aur denom me d^2 se

Answer 11

usse kya hoga...

Answer 12

shayad kuch aya...
a/b = c/ d
\[a^2/b^2 = c^2/d^2\]
\[a^2/b^2= (a^2+c^2)/(b^2+d^2)=a^2*(b^2+d^2)/b^2*(a^2+c^2)\]
aise hi
\[c^2/d^2=(a^2+c^2)(b^2+d^2)\]
ye bhi upar wale jaisa hi aye ga..
to dono ko equate kar de ge to a/b=c/d..
aa jaye ga shayad//
