用平方差公式,分子为8x^2n.分母最高次项为2x^2n,故所求极限为8/2=4.
f(x)=e^x-x 求证(1/n)^n+(2/n)^n+...+(n/n)^n
x^(n)*x^(n+1)+x^(2n)*x
若(x^2+1/x)^n(n∈N+,n
因式分解:(x^n+1)+(2x^n)+(x^n-1)
x^n+1-2x^n+x^n-1因式分解
x^n-1-2x^n+x^n-1因式分解
分解因式x^n-x^(n-1)+x^(n-2)
(x^4n/x^2n)*x^n
x^n-2x^n+1,因式分解
x^2n-3x^n
x^n*x^n+1*(-x)^2n*x+(-x)^2n+3x^2n-2*x
(-x)^3x^n-1+x^2n(-x)^3
因式分解:x^(2n)+(2x)^(n)+4^(n-1)
x^2n+(2x)^n+4^(n-1) 因式分解
m(x-y)^n+n(y-x)^2n因式分解
(x^2n-2)(x^8n+16)(x^2n+2)(x^4n+4)
(x^4n+16)(x^n-2)(x^2n+4)(x^n+2)=
(x^4n - 16) * (x^n - 2) * (x^2n + 4) * (x^n + 2)
