MAT 222 week 2 Discussion

  

Ashford 4: - Week 3 - Discussion 1

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 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 L

42     and 101

 

B     or K

96     and 60

 

C     or J

46     and 104

• 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.): 
  • Principal root 
  • Product rule 
  • Quotient rule 
  • Reciprocal 
  • nth 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.
 

  Carefully review the Grading Rubric for the criteria that will be used to evaluate your   discussion.
