Multiplication/Division of two variables

GAMS
1

Dear GAMS Users,

I have come across a situation where I have to multiply two positive variables.

But I am not able to do so, because doing so will lead the model to NLP. I don’t have NLP license.

Does anybody has easier solution?

Thanking you in advance

Dear Tushar,
May be you could try the approximation method in 7.7.
