PLEASE help me with logarithmic equations! (Inverses)?

Question

So the equation is f(x)=1/3 log2 x
(The two is subscript).

How do I get the inverse of this?? I think I just need to get y alone, but I'm not sure how to go about it. Can someone please help me and walk me through it? THANKS!!!

Yeah, the y is alone in THIS problem, but not in the inverse that I'm trying to get...

Answer 2

ok Amoung distinctive logarithm properties there is a normal one which I tell my pupils be looking out for and to memorize. In words it says.... while a huge determination B is raised to a log capability and the backside of that log is the comparable through fact the commencing huge style B then the respond is regardless of the Arguement A is of the log. Now reread th e above as you seem at the two examples under: ....Log(B) A B^..................= A ....Ln(e) A e^...............= A........bear in mind the sole base Ln could have is "e". SO e^(ln (x)) = e^(-3) is surely e^(ln(e) (x)) = e^(-3) OR ....ln(e) (x) e^.................e^(-3) as a result ........... "fancy math word we math human beings use" x = e^(-3) understand ???? If no longer please study under and use me as a coach enable me recognize in case you have questions approximately this difficulty or the different math issues. i'm an superb math instructor/coach focusing on making pupils speedier.....smarter......and greater ideal looking like myself. ok, merely speedier and smarter ....you do no longer choose to look like me. I coach loose on line by potential of using SKYPE. keeps me busy through fact moving from Florida to France. I make C, D , F pupils right into a, B , C pupils. I make large pupils even better. If fascinated merely enable me recognize a thank you to get in touch. If no longer it rather is large additionally. Mathcerely, Robert Jones "instructor of large pupils"

Answer 3

Where is the Y you need to get alone?

Answer 4

f(x) IS y, so y is already by itself!!
