Homework Wednesday, 1/9

Pre-Algebra: Pg. 214 #1 - 33 odd.  Answers are listed below, and I have included the even numbered answers if you would like to do them for extra practice.
Also, if you would like to do the worksheets I handed out in class the past two days, you may turn them in as optional assignments (you don't have to complete all of them).

Algebra: No homework.

Notes on reading the answers: I will use * to mean multiplication, so "two times three" would be 2 * 3.
I will use the ^ symbol to mean raising to a power, so "x to the 5th power" would be x^5.
Division and the fraction bar will use a /, with the numerator and denominator separated by parentheses if necessary.  "Two-thirds" would then be 2 / 3, and something like "8 times x squared over 9 times y" would be (8x^2) / (9y).
Alternate answers are possible, email me if you have any questions.

1. 3^3 (or, these can always be written without the exponent as 3 * 3 * 3)
2. (2^2) * 3 * 5 (remember, even numbers are not required tonight)
3. (2^2) * 3 * 7
4. (2^2) * 5 * 13
5. 25, not relatively prime
6. 1, relatively prime
7. 2, not relatively prime
8. 6, not relatively prime
