"Root[1+a #1+a^2 #1^5 &,1]" is to be read as the first root of the equation 1+a x1+a^2 x^5=0. The solutions to this and many similar equations cannot be given in a closed form or are extremely complicated. Sometimes ToRadicals[ ] may work. If you didn't have a symbolic parameter a in the equation N[ ] would work. Cheers -- Sjoerd On Feb 10, 12:54 pm, Nandhini <nandhini.gopa... at gmail.com> wrote: > Frnds, > Im very new to mathematica.
