(x^2n-2)(x^8n+16)(x^2n+2)(x^4n+4)
因式分解:8x^2n+1-12x^2n+4x^n(要过程,)
(x^4n/x^2n)*x^n
(8x^n+1-3x^n-1)-2(-x+9x^n+1-4x^n)=
因式分解:x^(2n)+(2x)^(n)+4^(n-1)
x^2n+(2x)^n+4^(n-1) 因式分解
(x^4n+16)(x^n-2)(x^2n+4)(x^n+2)=
(x^4n - 16) * (x^n - 2) * (x^2n + 4) * (x^n + 2)
因式分解4x^(n+2)-9x^n+6x^(n-1)-x^(n-2)
因式分解4x^n+2-9x^n+6x^n-1-x^n-2
(4x^n-2x^n-1-3x^n+2)÷(-5x^n-1)
x^n-1(3x^n+4x^n+1-5x^n+2)
因式分解:4/9x^n+2-8/27x^n
因式分解:2x^n-4x^n-1-8x^n-2
(-x^2n)(-x)^n=8^n,求2x^2+x-15/4x-10
数字信号处理,单位跃阶响应 已知h(n)= x(n-2) - x(n-4),s(n)=h(n)*u(n) s(n)是多少?
(4x^n-1 y^n-2)÷(-x^n-2 y^n+1)(1)(4x^n-1 y^n-2)÷(-x^n-2 y^n+1)(2)已知a^m=2,a^n=8,m,n为正整数,求a^m-n的值(1)(4x^n-1 y^n-2)^2÷(-x^n-2 y^n+1)
4x^n+2-9x^n+6x^n-1-x^n-24x^(n+2)-9x^n+6x^(n-1)-x^(n-2),n是整数且大于2
