I have the following expression
expr = x1^d1 * x2^d2 * x3^d3;
d1,d2,d3 can contain negative values/expression i.e. in general these
d1,d2,d3 may not be numerical values. Say
d1 = 4 d; d2 = -5 e; d3 = -6 d; with assumption d, e are positive.
Question : Is there any way to make two lists one containing positive exponent and other with negative exponent?
My current try is to use
Exponent for each one of these terms and test them for positive and negative.
