Note: Homework Hints are given only for the Level 1 and Level 2 problems.
However, as you go through the book be sure you look at all the examples in the text. If you need hints for the Level 3 problems, check some sources for help on the internet (see the LINKS for that particular section). As a last resort, you can call the author at (707) 829-0606.
On the other hand, the problems designated “Problem Solving” generally require techniques that do not have textbook examples.
There are many sources for homework help on the internet.

There are many problems throughout the text labeled IN YOUR OWN WORDS. Just relax; do not be afraid to give your opinion. For the most part, these questions do not have “right” or “wrong” answers. You should spend about five minutes in answering each of these questions.
See Example 1. What you should be thinking here is that you are using the definition of square root.
See the discussion between Examples 1 and 2 paying addition to the factored form of the number under the square root symbol. What you are looking for are factors which are perfect squares. It is a good idea to remember the first few perfect squares: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and 169. See Example 2.
See Examples 6 and 7a.
See Example 7b. Remember the number outside the radical symbol (3 in part a) is multiplied by the number using the radical symbol.
See Example 7e.
See Example 7g.
See Example 7f.
See Examples 7c and 7d.
See Example 7j.]
See Example 7ell and m.
See Example 7h and 7i.
See Example 7n.
See Example 3.
