（1）應該是(C）（2）31（3）-8a（4）(c）

答案應該是9吧我們老師沒有教

(1)2^6/4^3 = 2^6/(2^2)^3 = 2^6/2^6 = 2^(6-6) = 2^0 = 1(2)4^12 = 8^a = 2^(b+1)4^12 = (2^2)^12 = 2^24 = (2^3)^8 = 8^8故 a = 8, b+1 = 24則 a + b = 31.(3)(-4) × a^0 + (-4 × a)^0 = (-4)×1 + 1 = -3(4)2^3 - (-2)^3 = 8 - (-8) = 162^4 - (-2)^4 = 16 - 16 = 0(-2)^3 - (- 2^3) = -8 - (-8) = 0(-2)^4 - (- 2^4) = 16 - (-16) = 32(5)a = 3^555 = (3^5)^111 = 243^111b = 4^444 = (4^4)^111 = 256^111c = 5^333 = (5^3)^111 = 125^111∵ 256 > 243 > 125 > 1∴ b > a > c(6)9^3 + 9^3 + 9^3 + 9^3 + 9^3 + 9^3 + 9^3 + a = 9^4  = 7 × 9^3 +a = 9 × 9^3∴ a = 9 × 9^3 - 7 × 9^3 = 2 × 9^3 = 1458
