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%5E%284%2F2%29=sqrt%286%5E4%29=sqrt%286%5E2%2A6%5E2%29=6%2A6=36


4%5E%284%2F2%29=sqrt%284%5E4%29=sqrt%284%5E2%2A4%5E2%29=4%2A4=16


8%5E%284%2F2%29=sqrt%288%5E4%29=sqrt%288%5E2%2A8%5E2%29=8%2A8=64
