Root 3 + root 2 /root 3- root 2 = a+b root 6

5 + 2

Step-by-step explanation:

Given

Multiply numerator/ denominator by the conjugate of the denominator

The conjugate of - is +

= ← expand numerator/ denominator using FOIL

=

=

= 5 + 2 → with a = 5 and b = 2

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
