During this course 2011 - 2012 MATHEMATICS is being taught for 4º ESO.

Logarithms

While I was looking for a page where logarithms were explained, I found this webpage, and there they have our whole unit (because logariths are powers, and you must handle them right if you want to understand logarithms). I think it's a good explanation.
LOGARITHMS

I also found this videos about logarithms with a lot of examples and their properties:
EnlaceIntroduction to logarithms
Logarithms properties Part 1
Logarithms properties Part 2

I'd also like to propose some problems. There aren't many problems related to logarithms, so mine won't be very difficult or elaborated:
log a y = c; log a y^2 =??

    If I solve it, must I comment?
    I think I have the solution, but if I tell it here I'll spoil my partners if they didn't have the solution.

    Nicolás,
    I think you should share your solution with your partners and wait for their comments.

    No, sorry. I misunderstand the problem. I think the solution is "c times 2".

    In my opinion the solution is "(a^c).y "
