8×(X-60%)=64
(x+1)(x^2+1)(x^4+1)(x^8+1)(x^16+1)(x^32+1)(x^64+1)=?简便算法
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
30X-2X=84 5.8X-X=60 6.6X-5X=8 4X-X=24 1.5X-X=1
解下列方程 4(6x+3)=60 2x+1.5x=17.5 2x+23*4 8x-3x=105 (
帮我解几道方程、、8x-4(10-x)=44 60x+(100-x)*65=100*63 30x-20(180-x)=5
方程:10x-6*(8-x)=64
方程(x+1)(x+2)(x+3)(x+4)(x+5)(x+6)(x+7)(x^2+8x+9)+64=0
2X+4(8-X)=20 10X-6(10-X)=36 10X-6(16-X)=64 0.5X+0.1(8-X)=2 4
解方程1/x(x+1)+1/(x+1)(x+2)+...+1/(x+8)(x+9)=2x+3/x(x+9)
解方程:1\x(x+1)+1\(x+1)(x+2)+.+1/(x+8)(x+9)=2x+3\x(x+9)
解方程.(5x/x²+x-6)+(2x-5/x²-x-12)=7x-10/x²-6x+8
