Sept. 7 Class

Learning Goals: Review Exponent Laws

Today we went over some of the homework from yesterday.  You should now know how to solve all of the problems on the "Solving Equations" handout.

Here are solutions to a couple of the more tricky question that most people asked about:

Part 2 question (k).

Set each factor equal to zero to get three distinct roots.

Part 2 question (l).
In the first step, multiply each term by 6 to get rid of the denominators:

Now use the quadratic formula to get,

This cannot be simplified any further, so we leave the answer in this form.

Next we reviewed the exponent laws:

and worked on some examples.

For homework, please work "Reviewing the Exponent Laws" handout, questions #1-8 (eoo), 9, 14, 16

Have a safe weekend!
