计算：b^(3n-1)/a^(2n-1)×c÷b^(3n-2)/a^2n
^(3n-1)/a^(2n-1)×c÷b^(3n-2)/a^2n
=b^(3n-1)/a^(2n-1)×c×a^2n/b^(3n-2)
=bb^(3n-2)/a^(2n-1)×c×aa^(2n-1)/b^(3n-2)
=abc
再问： 不好意思，题打错了b^(3n-1)/a^(2n+1)×c÷b^(3n-2)/a^2n
再答： b^(3n-1)/a^(2n+1)×c÷b^(3n-2)/a^2n =b^(3n-1)/a^(2n+1)×a^2n/b^(3n-2)×c =bb^(3n-2)/aa^2n×a^2n/b^(3n-2)×c =bc/a
=b^(3n-1)/a^(2n-1)×c×a^2n/b^(3n-2)
=bb^(3n-2)/a^(2n-1)×c×aa^(2n-1)/b^(3n-2)
=abc
再问： 不好意思，题打错了b^(3n-1)/a^(2n+1)×c÷b^(3n-2)/a^2n
再答： b^(3n-1)/a^(2n+1)×c÷b^(3n-2)/a^2n =b^(3n-1)/a^(2n+1)×a^2n/b^(3n-2)×c =bb^(3n-2)/aa^2n×a^2n/b^(3n-2)×c =bc/a
计算：b^(3n-1)/a^(2n-1)×c÷b^(3n-2)/a^2n
分式计算：(b^3n-1 )*c/(a^2n+1)除以 (b^3n-2)/(a^2n)
计算 :(-0.5a^3b^2)(-4a^n+1 b^n c) 急
b^3n-1/a^2n-1×c÷b^3n-2/a^2n
已知n为大于1的自然数,计算b^3n-1c^3/a^2n+1 *a^2n/b^3n-2
计算：(-3a^n+1b^n)*(1/3ab)*(-a^2c)
计算[(a^m+1)(b^n)(c^2)]^3
b^3n-1 c^2/a^2n+1×a^2n-1/b^3n-2=
a^(n+1)b^n-4a^(n+2)+3ab^n-12a^2
定义数列An=x^n+y^n+z^n,则A(n+3)-3A(n+2)+b*A(n+1)-c*An=0
计算:(3a^n+2+6a^n+1-9^n)÷3a^n-1
a(n+1)=2an-a(n-1) 3bn-b(n-1)=n
