▼优质解答
答案和解析
(a^2b^2)*(ab^2)*2(ab^2)^2*a^3
=(a^2b^2)*(ab^2)*2(a^2b^4)*a^3
=2a^2b^2*ab^2*a^2b^4*a^3
=2a^(2+1+2+3)b^(2+2+4)
=2a^8b^8
3^100*(-1/3)^101
=3^100*(-1/3)^100*(-1/3)
=[3*(-1/3)]^100*(-1/3)
=(-1)^100*(-1/3)
=1*(-1/3)
=-1/3
=(a^2b^2)*(ab^2)*2(a^2b^4)*a^3
=2a^2b^2*ab^2*a^2b^4*a^3
=2a^(2+1+2+3)b^(2+2+4)
=2a^8b^8
3^100*(-1/3)^101
=3^100*(-1/3)^100*(-1/3)
=[3*(-1/3)]^100*(-1/3)
=(-1)^100*(-1/3)
=1*(-1/3)
=-1/3
