Question

LIM (sqrt(x+2)-2)/(x-2)
x == 2

Answer 1

use L'Hopital's rule Limit as x->2 of f(x)/g(x) = Limit as x->2 of f'(x)/g'(x)

Answer 2

take the derivative of both numerator and denominator and then take the limit. the answer is 1/(2*sqrt(2))

Answer 3

sorry, should be 1/4 haha

Answer 4

Ohhh, thank you so much. I have been stuck on it for like 30 minutes straight.

Answer 5

sorry too lazy to type the equation O_O

Answer 6

How about this one? Do you factor the top?
LIM (x^3-125)/(x^2-25)
x == 5

Answer 7

yeah, fator out (x-5) from BOTH top and bottom

Answer 8

Okay cool. thanks dude!
