We covered the classroom first. With 25 students in the class, we need everyone’s cooperation to have a good learning environment for everyone.

We covered the material about Exponents. The following are the important rules and definitions to memorize:

• a^m * a^n = a^(m+n)
• a^m / a^n  = a^(m-n)
• (a^n)^m = a^(nm)
• a^m * b^m = (ab)^m
• a^m / b^m = (a/b)^m
• a^0 = 1, a<> 0 (a to the power of zero is 1, as long as a is not zero)
• a^(-n) = 1 / a^n, a <> 0

With the above rules and defintions, we can simply expressions. We did several in-class exercises and the homework will be mostly about simplying expressions.

We also talked about exponents with variables, whose operation is no different, except that we use variables, like x, y, a, b, c, etc., to represent the things in the operation. Same rules and definitions apply.

For homework, it is on the workbook:

• Page 2, 4a, 4b, 4c, 6a, 6b, 7a, 7b, 7c
• Page 3, 8g, 8i, 9a, 9c
