2) 4^2 x 4^-2 =
3) 8^4 �8^6 =
4) (5^-1)^-3 =
5) 12^10 x 12^-12 =
6) (2^-3)(2^-2) =
Answer by oscargut(2103) (Show Source): You can put this solution on YOUR website!
1) 7^8 x 7^-3 = 7^(8-3) = 7^5 = 16807
2) 4^2 x 4^-2 = 4^(2-2) = 4^0 = 1
3) 8^4 �8^6 = 8^(4-6) = 8^(-2) = 1/64
4) (5^-1)^-3 = 5^(-1*-3)= 5^3 = 125
5) 12^10 x 12^-12 = 12^(10-12) = 12^-2 = 1/144
6) (2^-3)(2^-2) = 2^(-3-2) = 2^-5 = 1/32
