Error dividing polynomials in plot

Trying to plot
from 3 to 10 but the graph shows blank. The numerator and denominator plot seperately so I think I must be telling matlab to divide in the wrong way. Here is my code:

x3 = linspace(3,10,100);
piot(x3,(2*x3+1)/((3*x3-1).^(1/3)))

x3 = linspace(3,10,100);
y = (2.*x3+1)./((3.*x3-1).^(1/3));
plot(x3,y)

You just have to put ./ instead of / , it’s called element wise operation in MATLAB see https://www.mathworks.com/help/matlab/matlab_prog/array-vs-matrix-operations.html .
Remark: plot not piot.
