√3 / √6 + √2
to make the denominator whole number, you need to multiply with the opposite
so, it became √3 / √6 + √2 × √6 - 2 / √6 - 2
you multiply √3 and √6 - 2.
and multiply √6 + √2 and √6 - √2. if you multiply √6 and √6, it is 6. the same goes for √2.
The next step is √18 - √6 / 6 - 2.
√18 is the same as 3√2.
The answer is 3√2 - √6 / 4.
