Rationalize the Numerator:

{(Sq. Root of X+h) - (Sq. root of X) / h}

This is a bonus question!?

Help!?

Thank You!!!!!!!!!!

You rationalize the numerator in the same way that you

**rationalize a denominator**: by multiplying by the conjugate. So multiply, top and bottom, by:

$\displaystyle \sqrt{X\, +\, h}\, +\, \sqrt{X}$

Have fun! :D
