化简:(a^n+1-ab^n)/(a^2n+2-a^2b^2n)a^n+1a的(n+1)的次方后面有些也是化简:(a^n+1-ab^n)/(a^2n+2-a^2b^2n)a^n+1a的(n+1)的次方

化简:(a^n+1 -ab^n)/(a^2n+2 -a^2 b^2n)a^n+1a的(n+1)的次方后面有些也是
化简:(a^n+1 -ab^n)/(a^2n+2 -a^2 b^2n)
a^n+1
a的(n+1)的次方
后面有些也是

化简:(a^n+1 -ab^n)/(a^2n+2 -a^2 b^2n)a^n+1a的(n+1)的次方后面有些也是
(a^(n+1)-ab^n)/(a^(2n+2)-a^2b^2n)
=[a(a^n-b^n)]/[a^2(a^2n-b^2n)]
=[a(a^n-b^n)]/[a^2(a^n-b^n)(a^n+b^n)]
=1/[a(a^n+b^n)]
=1/(a^(n+1)+ab^n)
