Question 803723
if a= sqrt(3)+sqrt(2) / sqrt(3)- sqrt(2)
b= sqrt(3)- sqrt(2) / sqrt(3)+sqrt(2)


{{{(sqrt(3)+sqrt(2)) / (sqrt(3)- sqrt(2))+(( sqrt(3)- sqrt(2)) / (sqrt(3)+sqrt(2)))}}}


{{{((sqrt(3)+sqrt(2))^2+(( sqrt(3)- sqrt(2))^2))}}}/{{{((sqrt(3)- sqrt(2))*(sqrt(3)+sqrt(2)))}}}


{{{(5+2sqrt(6)+5-2sqrt(6))}}}/{{{3-2)}}}
