x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
2x+3x+4x+5x+x+6x+7x=100
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
1+x+x^2+x^3+x^4+x^5+x^6+x^7+x^8+x^9+x^10+x^11+x^12=97.8x+x^2+x^3+x^4+x^5+x^6+x^7+x^8+x^9+x^10+x^11+x^12=97.8 好多年没有用过过数学公式了 想不起来怎么算了 想知道 X值是多少
已知x=2π+1求 |x-1|+|x-2|+|x-3|+|x-4|+|x-5|+|x-6|+|x-7|+|x-8|+|x-9|+|x-10|
已知x=2π+1.求(X-1)+(X-2)+(X-3)+(X-4)+(X-5)+(X-6)+(X-7)+(X-8)+(X-9)+(X-10)
如果1+x+x^2+x^3=0,求x+x^2+X^3+x^4+x^5+x^6+x^7+x^8的值,
1+x+x^2+x^3+x^4+x^5+x^6+x^7+x^8+x^9+x^10+x^11=17.7这个方程怎么样求解?
请大神帮我解这个数独 题,我解了很久 了 ,最后 X X X X 3 X 1 5 XX X X X 7 8 6 X 92 9 X X X X X X 7X X X X 6 X 2 X 3X 1 3 7 2 9 4 8 X4 X 2 X 8 X X X X3 X X X X X X 6 48 X 6 3 9 X X X X X 7 1 X 4 X X X X
(x-5)/(x/7)+(x-2)/(x-4)=(x-3)/(x-5)+(x-4)/(x-6)
(4x+2)/x+(4x-22)/(x-5)=(x-6)/(x-4)+(7x+9)/(x+1)
解方程(x-2)/(x-3)-(x-3)/(x-4)=(x-5)/(x-6)-(x-6)/(x-7)
解方程 x+2/x+1+x+8/x+7=x+6/x+5+x+4/x+3
解方程:2x+4x+6x...+100x=1-(x+3x+5x+...+99x)
(x-1)(x-2)(x-3)(x-4)=(x+5)(x+6)(x+7)求X等于几?
因式分解 x^8+x^7+x^6+x^5+x^4+x^3+x^2+x=?
x-2/x-1+x-8/x-7=x-4/x-3+x-6/x-5
