~Apple exponent rule [ a^b * a^c = a^b+c ]
3^2-8+0
~Simplify
3^-6
~Use exponent rule [ a^-b = 1/a^b ]
1/3^6
~Simplify
1/729
Best of Luck!
If the cookies had been divided equally between the h grandchildren then each grandchild would receive 96/h cookies.
So Cindy received (96/h) - 5 cookies
2^3 * 2^-5 = 2^(3 + (-5) = 2^(3 - 5) = 2^-2
