Week 3 – Discussion45Your 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. Carefully review the Grading Rubricfor guidance on how your discussion will be evaluated.Simplifying Radicals [CLOs: 1]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(available for download in your online classroom) to complete this discussion. Please complete the following problems according to your assigned number. (Instructors will assign each student their number.)If your assigned number is 21On pages 575 577, 40 do the following problem 51/4 5-1/4On pages 584 585, 42 do the following problem please see file attach for this one 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 rootRefer to Inserting 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.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.
