(x-1)(x+1)=x^2-1,(x-1)(x^2+x+1)=x^3-1.已知x^4+x^3+x^2+x+1=0,求x^2010

解答
因为(x-1)(x^4+x^3+x^2+x+1) = x^5 - 1 = 0
所以x^5 = 1
故x^2010 = x^(5×402) = (x^5)^402 = 1^402 = 1
希望有用.
推荐
- 当x=2,1/2,3,1/3,4,1/4,…,2010,1/2010,2011,1/2011,时,
- 若x+x^2+x^3=-1 则x^2012+x^2011+x^2010+x^2009+…………+x^3+x^2+x+1=
- 1/x(x+1)+1/(x+1)(x+2)+1/(x+2)(x+3)+···+1/(x+2010+(x+2011)
- 规律:(x-1)(x^3+x^2+x+1)=x^4-1,已知:x^4+x^3+x^2+x+1=0,求x^2010 麻烦用简单的方法(有过程
- 已知|x-1|+(y-3)^2=0,说明x^2010+y^2010是5的倍数
- 已知单项式0.25x的b方乘y的c方与单项式-0.125ax的m-1方的和是0.625x的n方乘y的m方
