已知 X=4- 根号3 求 (X*X*X*X-6X*X*X-2X*X+18X+23) / (X*X-8X+15)的值
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
用递归法求y=x-(x*x*x/3!)+(x*x*x*x*x/5!)-(x*x*x*x*x*x*x/7!)+.
5x-0.5=8 [x-4.6]×2.3=9.338 3x-1.45=2x+1.45 3.5x+x-14=18.4
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
15x=23x-24 12+5x=3x-8 3(x-3)=9-(x+6)解 4+x=4x-17解
(2x-1)/(x-1)(x-2)=(x-5)/(x-2)(x-3) x/2x^2-11x-21=(x+7)/x^2-1
