Question

x=e^(3y)

I got to ln(x)=3yln(e), and when I use an online calculator to help me, they just switch ln to log for no reason :'(

Answer 1

wolfram notates ln as "log" unless stated otherwise

Answer 2

Ooooh =[

Answer 3

what is it your trying to do with this?

Answer 4

Well i'm given y=e^3x, and im finding the inverse.

Answer 5

Solving for y by inputting x for y, y for x. x=e^3y, then solving. ln(x)=3yln(e)

Answer 6

Not sure what to do from there!

Answer 7

ln and e are inverses of each other; so they cancel each other out, or rather they equate to "1" like 5/5:

ln(e) = 1

e^(ln(1))=1

Answer 8

once you know that, divide off that 3 and your set

Answer 9

So wait, just ln(x)/3=y?

Answer 10

yep

Answer 11

Thanks :D

Answer 12

youre welcome

Answer 13

I have another one D: I always just get stuck at the beginning.

Answer 14

x=log2y, is it 10^x/2=y?
