Logarithm game!
If you don't know logarithms yet, please go here: http://www.mathsisfun.com/algebra/logarithms.html
Okay! Questions!
Fill in the blank.
1) log4(___)=3
2) log2(81)=__

Star members have too many stars. So, if I congratulate new star members, so, that means I need more stars for my picture?

Re: Logarithm game!
Hi;
In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

Hi julianthemath;
I think you mean for 5

Re: Logarithm game!
5=11 6=625
Muxdemux, sorry about that. 
Bobbym, I don't mean that! 
Muxdemux, I think that is not correct in 6.
Anyways,
7. log3(___)=5
8. log6(64)=__

@julianthemath
The correct formula is , not loga(na) = n. This is what you seem to be confusing.

Okay, scientia. I might not do this well. Ask bobbym to close the thread.

I will keep it open a bit longer in case you change your mind.

Re: Logarithm game!
julianthemath, Have you see the fact that
logy logx
x = y which is still true for any positive base b (not 1) and positive x and y?
One might get some interesting variations on these log problems using this fact.
Writing "pretty" math (two dimensional) is easier to read and grasp than LaTex (one dimensional).
LaTex is like painting on many strips of paper and then stacking them to see what picture they make.
