We then took a quiz on Exponent rules we've been working on this week. If you were absent today, make sure to study over the weekend, and be ready to take this in class on Tuesday!

February 13: Power of a Power
Today we learned how to simplify terms with exponents to a power (Power of a Power). In this case, the rule we determined is shown below:

February 12: Quotient of Exponents

February 11: Product of Powers
Product of Powers, or multiplying terms with exponents, was the focus for today. The best strategy for this new concept is to start by writing each term out in expanded form. Then determine the number of factors and simplify! Sounds easy, right? Wait... it gets even easier!
Once we did a few examples together, many of us noticed a pattern- all we have to do is add the exponents! See? Told you it was even easier!
Product of Powers Rule:
Add the exponents and the base stays the same
ex: x m . x n = x m+n

February 10: Properties of Exponents
Today we had a guest teacher, so we reviewed what we covered yesterday: going from expanded notation to exponent notation and the converse. There were no new notes.

February 9: Exponents
Today we begin our Unit 6: Exponents and Scientific Notation. This is a 3 week long unit: the first 2 weeks will be devoted to learning the laws and properties of exponents, and the last week will be scientific notation followed by the Unit test on Friday, February 27.
Today's notes were an introduction to what exponents are, and we learned a few new terms: Exponent, Base, and Expanded Form.
The exponent of a number says how many times to use that number in a multiplication.
We also did an in class activity that is attached to the homework (first 2 pages) instead of taking a lot of notes. Everyone found it much easier to work examples together rather than take traditional notes.

The exponent of a number says how many times to use that number in a multiplication.
It is written as a small number to the right and above the base number.
