At first, I really really disliked this unit, jut because of the fact that I didn't like exponents. Yes, I know what you're thinking, "Who doesn't like exponents??" Well, i did. I didn't get how negative exponents worked, and now after reading over the stuff, and after I gave it a try, well.. I realized that it wasn't that hard to understand.

There aren't really a lot of things to remember for this unit, except for the fact that A LOGARITHM is an EXPONENT. Another thing to remember would be that an exponential function turns an exponent into a power, while a logarithmic function turns a power into an exponent.

These are the laws that we should know:

The Product Law

log

_{b}MN = log

_{b}M + log

_{b}N

The Quotient Law

log

_{b(M/N) = }log

_{bM - }log

_{bNThe Power Law}

log

_{b}M

^{k}= klog

_{b}M

We should also know that when no base is indicated, the base of the logarithm is base 10 .

Also, remember the

Change of base formula:

some formula's we should know about..

A = P(1+r/n)

^{t}

A = P

*e*

^{rt}

A = A

_{0}(model)

^{t}

A = A

_{0}(m)

^{t/p}

Well, yeah, that`s pretty much what we`ve learned in this unit. There are a few more, but I can`t really remember them at the moment. So I guess I`m off to study.
