(a-b)^m*(a-b)*[2(b-a)^3*(b-a)^5]^2/(a-b)^m怎么做?
(a-b)^m*(a-b)*[2(b-a)^3*(b-a)^5]^2/(a-b)^m怎么做?
(a-b)^m*(a-b)*[2(b-a)^3*(b-a)^5]^2/(a-b)^m怎么做?
(a-b)^m*(a-b)*[2(b-a)^3*(b-a)^5]^2/(a-b)^m
=(a-b)*[2(b-a)^8]^2
=(a-b)*4(a-b)^16
=4(a-b)^17
如果本题有什么不明白可以追问,
(a-b)^m*(a-b)*[2(b-a)^3*(b-a)^5]^2/(a-b)^m
=(a-b)^(m+1)*[2(b-a)^8]^2/(a-b)^m
=(a-b)^(m+1)*[4(b-a)^16]/(a-b)^m
=4(a-b)^(m+17)/(a-b)^m
=4(a-b)^17
(a-b)^m*(a-b)*[2(b-a)^3*(b-a)^5]^2/(a-b)^m
=(a-b)^m*(a-b)*[4(a-b)^6*(a-b)^10]/(a-b)^m
=4(a-b)^(m+1+6+10-m)
=4(a-b)^17
(a-b)^m×(a-b)×[2(b-a)^3×(b-a)^5]^2÷(a-b)^m
=(a-b)×{-2(a-b)^3×[-(a-b)^5]}^2
=(a-b)×[2(a-b)^8]^2
=(a-b)×4(a-b)^16
=4(a-b)^17
(a-b)^m*(a-b)*[2(b-a)^3*(b-a)^5]^2/(a-b)^m
=*(a-b)*[2(a-b)^3*(a-b)^5]^2
=4(a-b)^(1+6+10)
=4(a-b)^17
