Am I retarded, /wsr/? Why is this answer wrong? I double checked

It's natural log, aka ln. Since you're dealing with an automated system, they're probably looking for ln and not tolerant enough to accept "log" as meaning ln. Historically, "log" by itself has referred to base 10.

That was it.

So when you integrate 1/x, it's always ln(x), not log(x)?

>>374914
Just googled it. Apparently e was discovered because of this problem, which is why it is used instead of 10.

Thanks btw.

Congrats on starting your homework on the first day of the three day weekend, you're a better man than me.

log(x) without a specified base can refer to log base 10, log base e or even log base 2 depending on the context. Webassign (or whatever online homework program you're using) will treat log(x) as log base 10. So in answer to >>374916 you're correct that the integral of (1/x) is the natural log of x, it's just a difference in notation that those shitty programs are intolerant of.
