1. The problem statement, all variables and given/known data i have a problem i tried to solved about 3 days and i couldn't ... here it is : (exp(x)/x^3)=2x+1 2. Relevant equations 3. The attempt at a solution ((e^x)/(x^3))=2x+1 > e^x=2x^4+x^3 >> (x=ln(2x^4+x^3) or 2x^4+x^3-e^x=0) ,, is it possible to get the zeros from the 2 solutions without graphing ??
