Question

Evaluate the limit

Answer 1

Just plug 4 in where there's an X and simplify.

Answer 2

I can't. If I try to multiply the conjugate and simplyfify the denominator still equals x-4 so I can't solve.

Answer 3

Ohh, I have to do this WITHOUT L'hopital's rule.

Answer 4

because we get 0/0, so we can use L'hopital's rule ....

Answer 5

I said without L'hopitals rule :P .

Answer 6

ok, nope...
we can multiply that praction with konyugate of sqrt(29-x)-5

Answer 7

I tried that but then I get

\[\frac{ (\sqrt{29-x})(\sqrt{20-x}-4}{ 4-x}\]

Answer 8

There should be a bracket after 4.

Answer 9

ok,
