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!
