HAPPY BIRTHDAY, MR. O'BRIEN!!

Schedule:
- QUIZ!
- Homework questions
- In class questions

Today in class:
Today, we took a homework quiz that everyone loved doing. The questions focused on logarithms and their properties, as well as some nifty tricks we've learned along the way. We then began to work on the in class questions in small groups, just to make things easier. In case you forgot to write them down, here they are:
[Descending order signifies the difficulty]
Page #253: 101, 97, 95, 91, 87, 59, 55, 53, 39, 33.

However, we DID take a short break to go over some homework problems. Mainly, we reviewed how to do logarithms algebraically using the properties of exponents. Here are some notes!

1. If two things are equal, you may log them.

You can do this:


Ding ding ding! That means that you can them do the properties of logs to get through this one, which should really come in handy.

2. Substituting a variable for a series of computations is WAY easier. For example, if you have you can say . Ta-da! This helps when doing equations such as number fifty-seven on the homework [phew] since you could in theory do this:

Let .



Isn't that so much nicer?

3. You can use the quadratic formula in conjunction with the One-to-One or the Common Sense property! Yay! This is sort of obvious, but it's a good thing to remember when you're stuck & can't decide what to do.

After we finished reviewing some homework [#'s 27, 57, 65, 81, & 99], we began to work on our in class problems again. Please note: if any of these are not finished during class, they ARE NOT homework over vacation! However, they do need to be done for class on TUESDAY. It is also good to remember that quarter two projects are posted & available for review. DON'T FORGET!

Have a great Thanksgiving!

[Happy scribing, Annie!]
