limit as x approaches 9 of (8/(sqrt(x)3))  (48)(x9)

Math 
MathMate,
Check for type, I believe the question should read:
(8/(sqrt(x)3))  (48)/x9)
=(8(sqrt(x)+3)/(x9) 48/(x9) ... multiply top & bottom by sqrt(x)+3
=(8sqrt(x)24)/(x9)
=(8(1/2)/sqrt(x)) / 1 ... diff. top and bottom, de l'hÃ´pital's rule
=4/3
