lnγ1=α1x2+(1/2)α2x2^2+(1/3)α3x2^3+...

lnγ2=β1x1+(1/2)β2x1^2+(1/3)β3x1^3+...

Applying the Gibbs-Duhem equation with ignoring coefficients αi's and βi's higher than i=3, we can obtain α1=β1=0, β2=α2+α3, β3=-α3

I don't know how that relationship between coefficients is derived.

Also, what would be the relationship when higher than i=4 is ignored?

Please help!
