Help Please. Simplify Radicals, Square Roots

Here are ten questions from my textbook. Could someone help and break each problem step by step so I understand how to do it. Thank you in advance! And were not allowed to use a calculator either....

1)

2)

4)

6)

7)

8)

9)

10)

Do you have no idea how even to get started on any of these? Did your class not cover this material? Did you text ask questions over topics it doesn't cover? Are you requesting links to lessons on these topics? I would guess so....

Try the following to get the step-by-step instuctions you have requested:

. . . . .Google results for "simplifying radicals"

. . . . .Google results for "solving rational equations"

. . . . .Google results for "distance word problem"

(Note: The lessons in the listing provided by the first link will help with questions (1), (7), (8), and (9). The lessons in the second link will help with (2) and (4). The third link will help with (6) and (10).)

Once you have studied through some lessons and learned the basic terms and techniques, please attempt the exercises. If you get stuck, please reply showing all of your work and reasoning.

Thank you.

Eliz.
