a^2表示a的平方
a^x表示a的x方
1.{[a^(x-1)]*[b^(y+1)]}^3=[a^(3x-3)]*[b^(3y+3)=a^9*b^6
所以3x-3=9
3y+3=6
x=4 y=1
2 {[ (-x)^2]*[A}]^3=[(x^2)*A]^3=(x^6)*(A^3)=x^6*y^3
所以A=y
3.[(4a)^4]^2m=(4a)^(8m)=[4^(8m)]*[a*(8m)]
因?yàn)?=2^2
所以[(4a)^4]^2m=(4a)^(8m)=[4^(8m)]*[a*(8m)]
=(2^2)^(8m)*[(a^2m)^4] a^(2m)=4
=2^(16m)*(4^4)
=[(2^m)^16]*(4^4)
=(3^16)*(4^4)
