In this discussion, you will simplify and compare equivalent expressionswritten both in radical form and with rational (fractional) exponents.Read the following instructions in order and view the example to complete this discussion. Please find the rational exponent problems assigned…. – Simplifying Expressions Involving Variables-# 68. Simplify each expression. Write your answers with positive exponents. Assume that all variables represent positive real numbers.#80. READ DIRECTIONS THOROUGHLY MAT222.W3.DiscussionExample.pdfSimplify 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 Symbolsfor guidance with formatting. Be aware with regards to the square rootsymbol, you will notice that it only shows the front part of a radicaland not the top bar. Thus, it is impossible to tell how much of anexpression 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 9is under the radical with the 12 or not. Therefore, we must specifywhether we mean it to say √(12) + 9 or √(12 + 9), as there is a bigdifference between the two. This distinction is important in yournotation.Another solution is to type the letters “sqrt” in place of the radicaland use parenthesis to indicate how much is included in the radical asdescribed in the second method above. The example above would appear aseither “sqrt(12) + 9” or “sqrt(12 + 9)” depending on what we needed itto say.
