(-1/4) ^-12 : (- 1/4)^-10 : (-1/4)^-1= (-1/4)^(-12 - (-10) - (-1)) = (-1/4)^(-12 + 10 + 1)
= (-1/4)^(-1) = (-4)^1 = -4

a = 4^(-2) * 4^4 * 4^(-3) = 4^(-2 + 4 - 3) = 4^(-1) = 1/4
b = 8^(-4) : 8^(-3) = 8^(-4 + 3) = 8^(-1) = 1/8
b : a = 1/8 : 1/4 = 1/8 * 4/1 = 4/8 = 1/2 ------ odpowiedx

6 * (6^8 + 6^9 + 6^10) = 6 * 6^8 ( 1 + 6 + 6^2) = 6^9 * (1 + 6 + 36) = 43 * 6^9
