Question

( frac{a-frac{1}{a^{2}}-frac{2}{sqrt{a}-frac{1}{sqrt{a}}}{a sqrt{a}}-frac{1-frac{1}{a^{2}}}{sqrt{a}+frac{1}{sqrt{a}}}}{frac{a^{3}-1}{a^{2}} times frac{sqrt{a}}{a-1}-frac{2}{a sqrt{a}}-frac{left(a^{2}-1right) times frac{sqrt{a}}{a^{2}}}{a+1}}{frac{a^{2}+1+a}{a sqrt{a}}-frac{2}{a sqrt{a}}-frac{(a-1)}{a sqrt{a}}}{frac{a^{2}+1+c-2}{a sqrt{a}}-a+1} )
( frac{a^{2}}{a sqrt{a}} )
( sqrt{a} )

# a-a 2 al2 - a -1/2 a3/2 1-22 a 2 + a-1/2
