More Logarithm



When I was looking for webpages of logarithm I found that one that contains a lot of examples of the logarithm rules and other things. I hope that it can help you to understand better how to do it.

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 =??

15 / 11 / 11 RATIONALIZING RADICALS

iF YOU NEED SOME HELP FOR RAZIONALIZING RADICALS, YOU CAN  PRACTISE SOME EXERCISES:


14 / 11 / 11 EXERCISES OF RADICALS

We check in class all the exercises you have for homework. 
But if you have any problems, HERE, you will find the correction for some exercises:


11 / 11 / 11 GOOGLE GROUPS

I´ve opened a group for you to discuss maths questions and possible problems with maths.
I think it can be very useful. Good luck!



7 / 11 / 11 POWERS & RADICALS

Let´s start a new lesson!

As a warm up, we´ll remember the exponents rules:


Below, you will find very useful links in order to learn some new concepts:


And, now a specific calculator for radicals:
