Answer 1

                   a - b                            (a^(1/2)+b^(1/2))*(a^(1/2)-b^(1/2))
---------------------------------------------- = ---------------------------------------------------- =
a^(1/2)*b^(1/2)*(a^(1/2)+b^(1/2))         a^(1/2)*b^(1/2)*(a^(1/2)+b^(1/2))
   a^(1/2) - b^(1/2)
= -----------------------
    a^(1/2)*b^(1/2)
