Fractional Exponents

This class we learned about fractional exponents.

What fractional exponents do is give us another method of writing radicals.

The mathimatical way of saying it is to take the denominator of the fraction

and use it as the index of the radical, like this:

 271/3 = 3√27

All you do is take The 3 from the 1/3 and put it in front of the radical,

which it is now called the index.

271/ = 3√27

Now the one that is left over you put behind the 27, so what you're 

doing is just grouping the 27 and 1 together, and putting it in the radical,

and they are both called the radicand.

=3√271

Because 271 equals 27, and mathematicians are lazy, if something times itself 

equals the same number, you don't have to put it.
