#### Description

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 the example to complete this discussion:

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 L42 and 101

B or K96 and 60

C or J46 and 104

D or I94 and 62

E or H52 and 102

F or G90 and 64

M or Z38 and 72

N or Y78 and 70

O or X44 and 74

P or W80 and 68

Q or V50 and 76

R or U84 and 66

S or T54 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. Use bold font 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.):

oPrincipal root

oProduct rule

oQuotient rule

oReciprocal

onth root

Refer to Inserting Math Symbols for guidance with formatting. Be aware that 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. Thus 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.

Your initial post should be at least 250 words in length. Support your claims with examples from required material(s) and/or other scholarly resources, and properly cite any references. Respond to at least two of your classmates posts by Day 7.
