ax_{1}^{a-1}x_{2}^{1-a}/(1-a)x_{1}^{a}x_{2}^{-a }= p_{1}/p_{2 }Hey guys. Stuck with this problem as I have forgotten my differentiation rules. I want to be able to show how to cancel down the equation so that it reads

a/(1-a) . x_{2}/x_{1}= p_{1}/p_{2}

It would be great if someone could give me a step by step breakdown and remind me which rules I need to use here. Thank you

(sorry I didnt know how to use the mathematical script)
