## Re: logaithm help.

??? You will accept 3> 1 won't you? And square root is an increasing function so . In fact, it is not at all difficult to use a calculator to see that .

Or do you mean " "?

Obviously both and give the same thing and**provided**that a is positive becauser log(a) is not defined for negative a.

Edit: Ah yeah, I totally forgot about looking at that part. Thank you.
