Is that or ? I'll assume its the first one since we are supposed to rationalise a denominator. Now times top and bottome by to rationalise the denominator.
I think it's : right??
Sorry, I meant: 1/(2√7 + 2√3) - 1/(3√7 + √3) LOL, I was thinking of putting brackets but hesitated.

Now to rationalise the denominator times the fraction (bottom and top) by the conjugates of the two surds to make the two factors rational. Now, I leave it up to you to expand the top...
