# week 3 discussion

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.

problem:

If the last letter of your first name isOn pages 576 – 577, do the following problems A or L42 and 101B or K96 and 60C or J46 and 104D or I94 and 62E or H52 and 102F or G90 and 64M or Z38 and 72N or Y78 and 70O or X44 and 74P or W80 and 68Q or V50 and 76R or U84 and 66S or T54 and 100Simplify 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.):Principal rootProduct ruleQuotient ruleReciprocalnth 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.
