主题： How to remove terms of some order
Suppose I have complicated expression with sums, products...etc
and to simplify my expression I want ro remove terms of some certain order from denominator...how do I do? I tried simple example but it did no help:
[(1/m)+1/m^2][(1/m)+1/m^3] so if I dont want term of order m^-5 how do I remove it? I tried Simplify[%/.(1/m)^5- >0]but.. no result
I do something wrong?
