Is this significantly different from the last where the 2 was a 1?

No. Using the method found here we may obtain a general solution for $\displaystyle \int x\sqrt{a\sqrt{x}}\,dx;\,a\sqrt{x}\ge0;\,a\in\mathbb{R}$ Though giving a more complicated result, that method can also be adapted to give a solution for $\displaystyle \int x\sqrt{ab\sqrt{x}}\,dx;\,ab\sqrt{x}\ge0;\,a,b\in\mathbb{R}$
