Question 854111: I'm a freshman in college and taking Math 121 (college algebra) online. This is a seven week course and I could really use someone to explain the steps out to me rather than be extremely vague like the online course does. For example there is a four over the beggining of the radical sign then under the radical sign is x%5E24z%5E28+%2F+81and it is askin me to simplify the following radical expression.

Is this it?
root%28+4%2C+x%5E24z%5E28+%2F+81+%29+
If so:
root%28+4%2C+x%5E24z%5E28+%2F+81+%29+=+%28+x%5E24%2Az%5E28+%2F+3%5E4+%29%5E%281%2F4%29+
+%28+x%5E24%2Az%5E28+%29%5E%281%2F4%29+%2F+%28%28+3%5E4%29%5E%281%2F4%29+%29+
+%28+x%5E%2824%2F4%29%2Az%5E%2828%2F4%29+%29+%2F+3%5E%284%2F4%29+
+%28+x%5E6+%2A+z%5E7+%29+%2F+3+
------------------------
The only rules used here are:
+%28+a%5Eb+%29%5Ec+=+a%5E%28b%2Ac%29+
and
+%28+a%2Fb%29%5Ec+=+a%5Ec+%2A%28+1%2Fb%29%5Ec+
