Answer:

5 + 2
√(6)

Explanation:

Given


(√(3)+√(2) )/(√(3)-√(2) )

Multiply numerator/ denominator by the conjugate of the denominator

The conjugate of
√(3) -
√(2) is
√(3) +
√(2)

=
((√(3)+√(2))(√(3)+√(2)) )/((√(3)-√(2))(√(3)+√(2)) ) ← expand numerator/ denominator using FOIL

=
(3+√(6) +√(6)+2 )/(3-2)

=
(5+2√(6) )/(1)

= 5 + 2
√(6) → with a = 5 and b = 2
