Answer 1

Is it a?

Answer 2

hmm graph it on google

Answer 3

is that log base 5 x

Answer 4

Yes!

Answer 5

I think that it's A...not completely sure. Do you agree @timo86m

Answer 6

well that is just ln(x)/ln(5) graph it see if you get that range

Answer 7

I thought it was A, so that`s what I`ll go with ;P

i dont think so it seems to be convergin to 3. something

Answer 9

log_5 625 is 4.

Answer 10

lets take a limit

Answer 11

yeah it is a since the limit as it aproaches infinity is infinity :)

Answer 12

yay I was right. Thanks (:

Answer 13
