Question 89591


   2 / √[3] + √[2] 

     rationalising factor of sq rt3+ sq rt 2 = sq rt 3- sq rt 2

     multiply and divide by sq rt 3 - sq rt 2

    2(sq rt 3- sq rt 2)/( sq rt 3+ sq rt 2.)(sq rt 3- sq rt 2)

   = 2( sq rt 3- sq rt 2)/(sq rt 3)^2- (sq rt 2)^2

   = 2(sq rt 3- sq rt 2)/3-2

   = 2(sq rt 3- sq rt 2)/1

   = 2(sq rt 3- sq rt 2)
