Integration: 1/((x^(1/2)-x^(1/3))

[Bohn507]

I have no idea where to start with this. Sorry about the format, I don't know where to make it into an easier to read style.

1/((x^(1/2)-x^(1/3))

The problem is: \int \dfrac{1}{\sqrt{x} - \sqrt[3]{x}} dx

Click on show steps and that's it.

See LaTeX for formatting your equations here.

Thank you!

Or, you could do as follows:
Introduce:
x=u^{6}\to\frac{dx}{du}=6u^{5}\to{dx}=6u^{5}du
Then,
\int\frac{dx}{\sqrt{x}-\sqrt[3]{x}}=\int\frac{6u^{5}}{u^{3}-u^{2}}du=\int\frac{6u^{3}}{u-1}du=6\int({u}^{2}+u+1+\frac{1}{u-1})du
which is easily integrated.
