Hope u like my process =====================
Taking log on both sides we get _________________________
p.log(x) + q.log(y) = (p+q).log(x +y)
Differentiating both sides by x, we get =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Again Differentiating in both sides we get!! --------------------------------------------------------------- See the pic.. _-_-_-_-_-_-_-_- Hope this is ur required answer
