Your initial discussion thread is due on Day 3 (Thursday) and you have until Day 7 (Monday) to respond to your classmates. Your grade will reflect both the quality of your initial post and the depth of your responses.

Simplifying Radicals

In this discussion, you will simplify and compare equivalent expressions written both in radical form and with rational (fractional) exponents. Read the following instructions in order and view theexampleto complete this discussion.Please find the rational exponent problems assigned to you in the table below:

If the last letter of your first name is	On pages 576 577, do the following problems
A or L	42 and 101
B or K	96 and 60
C or J	46 and 104
D or I	94 and 62
E or H	52 and 102
F or G	90 and 64
M or Z	38 and 72
N or Y	78 and 70
O or X	44 and 74
P or W	80 and 68
Q or V	50 and 76
R or U	84 and 66
S or T	54 and 100

• Simplify each expression using the rules of exponents and examine the steps you are taking.
• Incorporate the following five math vocabulary words into your discussion. Useboldfont to emphasize the words in your writing (Do not write definitions for the words; use them appropriately in sentences describing the thought behind your math work.):
  • Principal root
  • Product rule
  • Quotient rule
  • Reciprocal
  • nth root

Refer toInserting Math Symbolsfor guidance with formatting. Be aware with regards to the square root symbol, you will notice that it only shows the front part of a radical and not the top bar. Thus, it is impossible to tell how much of an expression is included in the radical itself unless you use parenthesis. For example, if we have 12 + 9 it is not enough for us to know if the 9 is under the radical with the 12 or not. Therefore, we must specify whether we mean it to say (12) + 9 or (12 + 9), as there is a big difference between the two. This distinction is important in your notation.

Another solution is to type the letters sqrt in place of the radical and use parenthesis to indicate how much is included in the radical as described in the second method above. The example above would appear as either sqrt(12) + 9 or sqrt(12 + 9) depending on what we needed it to say.

Last letter is y

#70. a1/2 over a^2
