Rewrite using only positive exponents:
1). a%5E3%2Ab%5E%28-2%29%2Fa%5E%28-4%29 You can change the sign of the exponent by moving the factor up or down.
a%5E3%2Ab%5E%28-2%29%2Fa%5E%28-4%29+=+a%5E3%2Aa%5E4%2Fb%5E2 Simplifying, this becomes:
highlight%28a%5E7%2Fb%5E2%29
2). %285x%5E2%29%5E%28-1%29+=+highlight%281%2F%285x%5E2%29%29
3). b%5E0%2Aa%5E%28-2%29%2Ac%5E3 Recall that anything to the zero power is equal to 1, sob%5E0+=+1 so we get:
highlight%28c%5E3%2Fa%5E2%29
