Question

$x^{3} y^{4} = (x + y)^{7}$

Chapter: Differentiation
Standard : 12

Answer: y/x

Please don't give useless answer. It's a Request.

PLEASE SOLVE IT

Answer 1

take log both side
it becomes

logx^3y^4=log (x+y)^7. {:: log a^n =n loga }

3logx+4logy =7log(x+y). {::log ab =log a +log b}

different tiate wrt to dx
3/x+4ydy/dx = 7(1+dy /dx)/(x+y)
okkkkkk

solve it more.
