To whom it may concern

I have used Mathematica to provide the roots of a 4th power polynomial of the form x^4+ax^3+bx^2+cx-d=0. I have two questions. Firstly, after assigning values to the coefficients, how do I get Mathematica to return the answer as a discrete number? For example, (and the equations I have are much more involved than this) I want to see an answer of 0.2937 instead of something like (2^(2/3)/3^2)*(4/3^(1/3))^0.5. If I can do this I can identify the physically meaningful root.

Secondly, I wish to insert the root equation into other equations I use to generate and analyze experimental data. Can these large Mathematica equations be exported into the other programs I commonly use such as Sigmaplot, Origin or Excel?

Any assistance would be greatly appreciated
