Hi Khan Academy,

It would seem there may be an issue with the answer formats on exponents 2. I could be completely wrong(which wouldn't suprise me), my math isn't great but i thought i'd point it out. An example of one of the questions i got was, what's 5 to the pow of 6? i got 1/15625. This was an incorrect answer format, the answer was just the denominator. Now it would seem everytime i get a question where the answer results in 1 over some number, the system seems to pick and choose the correct answer format.. sometimes the correct answer will be 1 over some number.. and other times it won't; i'd have to type in only the denominator as the correct answer format. I had the question 1/4 to the pow 3 and i got the answer 1/64. So seeing as my previous question answer format was just the denominator, i put in 64 for the answer. It was the wrong format, the correct format was 1/64. If i'm missing something stupidly easy here which would explain why i'm having these problems, please remove this :]
