Do you know what rational means?
|dw:1351750351911:dw|
|dw:1351750674780:dw|
But what does it equal as a rational exponent?
|dw:1351751110425:dw|
|dw:1351751331010:dw|
|dw:1351751362625:dw|

It's fine, the original question states: Create your own term using a rational exponent and then convert it to a radical expression. Explain, in complete sentences, how the expression was converted. You created the term cbrt(27), they want yo to be able to convert to rational exponents, so 27^(1/3) Then just explain how you converted it.
sqrt ---> square root cbrt ---> cube root
Yes it works... the cube root of 27. Just say in words how you would convert from a rational exponent to a radical.
I gottta go to bed... :( i think you can handle the rest?? It's not a formula, its just the degree of the radical goes to the denominator of the rational exponent, and the degree of the radicand goes to the numerator of the rational exponent. http://www.purplemath.com/modules/exponent5.htm
