                     272/3

Since 27 = 33, substitute (33) for 27

                   (33)2/3

Remove the parentheses by multiplying the outer exponent
2/3 by the inner exponent 3, and since 2/3 × 3 = 2 we have

                     32  

or 

                      9

27%5E%282%2F3%29
you can read this as
%2827%5E2%29%5E%281%2F3%29
or
%2827%5E%281%2F3%29%29%5E2
both are valid- the 2nd is most useful
27%5E%281%2F3%29+=+3 since 3*3*3 = 27
3%5E2+=+9
