+23247 94 / 96 = 9-2 (when dividing numbers with the same base, subtract exponents)
9-2 = 1/92 = 1/81 = 0.012345679012...
Or: 94 / 96 = 6561/531441 = 1/81 = 0.012345679012...
You need to simplify the answer and then solve. When dividing by like numbers (I'm not sure whether of not they have to be alike but I'm pretty sure it doesn't matter in this particular problem), you can subtract the exponents. Because you're subtracting 6 from 4, you're going to get a negative number for an exponent: -2. Then, you make the -2 a positive 2 by turning it into a fraction, so it'll be 1 over 9 to the second power. You'll get 1 over 81. That's your answer in fraction form.
