Hi. I'm having a problem with fractional exponents and higher order roots in sage.
If I put (-2)* (6/2), sqrt((-2)* 6), the result is (-8, 8). That's wrong, since sqrt[ (-2)**6 ] = (-2) * (-2) * (-2) = -8. Does anyone know why this is happening, please?
I need to plot a function like V(x) = x^[ (2n+1)/n ], where n is interger. However, sage returns the error 'negative number to a fractional power not real' and plot only the positive branch.
