SOLUTION: 1/(sqrt(x-4)+sqrt(x-3))
please simplify
i believe that i have to multiply the top and bottom by the denominator over itself to get rid of the square roots but i am not sure

You can put this solution on YOUR website! 1/(sqrt(x-4)+sqrt(x-3))
----------
Multiply numerator and denominator by sqrt(x-4)-sqrt(x-3)
----------
= [sqrt(x-4)-sqrt(x-3)]/[sqrt(x-4)+sqrt(x-3)]
----------
= [sqrt(x-4)-sqrt(x-3)]/[(x-4)-(x-3)]
---------------
= [sqrt(x-4)-sqrt(x-3)]/(-1)
-----
= sqrt(x-3)-sqrt(x-4)
