How to expand (x1.95)(x4)(x+7.98) in the Prime?
Hey guys, I'm having a problem expanding expressions involving decimal numbers.
I type the expression (in CAS) then I put to simplify, but it doesn't. It returns the same expression, but if I do with natural numbers it does expand. For example, for (x1.95)(x4)(x+7.98) it should return x^3+2.03 x^239.681 x+62.244, but it doesn't, it returns the same input expression. But for example, if I type (x1)(x4)(x+7) and put to simlify, it does return the expanded form x^3+2 x^231 x+28 Does anyone know how to overcome this? Thanks a lot!
