Question 413526
Whenever you see a fractional exponent, remember that the {{{top}}} number is the {{{power}}}, and the {{{lower}}} number is the {{{root}}} (if you're converting back to the radical format). 


{{{6^(4/2)=sqrt(6^4)=sqrt(6^2*6^2)=6*6=36}}}



{{{4^(4/2)=sqrt(4^4)=sqrt(4^2*4^2)=4*4=16}}}



{{{8^(4/2)=sqrt(8^4)=sqrt(8^2*8^2)=8*8=64}}}
