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. Please find the rational exponent problems assigned....
- Simplifying Expressions Involving Variables-
Simplify each expression. Write your answers with positive exponents. Assume that all variables represent positive real numbers.

- 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
- nth root
Refer to Inserting Math Symbols
for 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
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
