I assume the problem is:
8.2%5E%287%2F4%29%2F8.2%5E%282%2F7%29
The rule for exponents when dividing is to subtract the exponents. Using this rule we get:
8.2%5E%28%287%2F4%29-%282%2F7%29%29
Since the exponents are fractions, they need to have common denominators before we subtract them:
8.2%5E%28%2849%2F28%29-%288%2F28%29%29
which simplifies to:
8.2%5E%2841%2F28%29
