Topics:
Simplifying radicals (including higher roots)
Adding and subtracting radicals
Multiplying radicals
Dividing radicals (simple case)
Here are the notes I handed out in class: OperationsWithRadicals
The problems we worked on in class were (some of) the even-numbered problems from the textbook, page 39
Homework homework yes you have homework
Please make sure to work on the WeBWorK assignments which are due tomorrow night, but start them now! There will be a quiz on adding/subtracting and multiplying radicals tomorrow.
Also, do the following problems on dividing radicals: assume all variables are $\ge 0$
(1) $\frac{\sqrt{57}}{\sqrt{19}}$
(2) $\frac{\sqrt{2x^{3}}}{\sqrt{18x}}$
(3) $\frac{3\sqrt{2x}}{\sqrt{8x}}$
(4) $\frac{5\sqrt{30}}{10\sqrt{120}}$
