Simplify radical expression

[Math Tutor]

Simplify the following expression:
[tex]\frac{(x^{2} - 1)^{2} \sqrt{x+1}}{(x-1)^{\frac{3}{2 }}}[/tex]

[radicals]

The expression is equal to:
[tex]\frac{(x - 1)(x + 1)\sqrt{x+1} }{(x-1)\sqrt{x-1}}[/tex][tex]= \frac{(x + 1)\sqrt{x+1} }{\sqrt{x-1}}[/tex]
[tex]= \frac{(x+1)\sqrt{x^2 - 1}}{x-1}[/tex]
