Let $gamma in C^2(mathbbR^n)$. I would like to show the algebraic identity
$$gamma^-1/2( nabla cdot gamma nabla gamma^-1/2 ) = Delta - fracDelta gamma^1/2gamma^1/2.$$



I know this might seem trivial if the trick is seen but I seems to be stuck in some loophole. Could anyone gives a brief step through? Any hints will be much appreciated. Thanks!
