您好,我想咨询几道题:x+6=10,x-8=15,x-26=38,x+14=27,a-15=21,
y+17=29,n+13=28,m-25=33,x+3=12,y-6=19,m-11=20,a+14=32,n+18=35,t-26=31,x-2.4=3.6,y+4.2=8.7,3x=15,2a÷9=4,2x+3x=15,3.7x+2.9x=19.14,24t-16t=29.6,
y+17=29,n+13=28,m-25=33,x+3=12,y-6=19,m-11=20,a+14=32,n+18=35,t-26=31,x-2.4=3.6,y+4.2=8.7,3x=15,2a÷9=4,2x+3x=15,3.7x+2.9x=19.14,24t-16t=29.6,
x+6=10
x=10-6
x=4
x-8=15
x=15+8
x=23
x-26=38
x=38+26
x=64
x=10-6
x=4
x-8=15
x=15+8
x=23
x-26=38
x=38+26
x=64
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
1x+2x+3x+4x+5x+6x+7x+8x+9x+10x+11x+12x+13x+14x+15x=550
x+x=x+15
(X+X)+(X-X)+(X*X)+(X/X)=100
5x+15/x^2+x-6=A/x-2+B/x-3
a*b=2×a+b 计算x*2x*3x*4x*5x*6x*7x*8x*9x=3039 x=
X/15 + X/12 + X/10 = 1365,求X,
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
y=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10)的导数在x=1
设函数f(x)=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10),
(x+7/x+6)+ (x+9/+x+8)=(x+10/x+9)+(x+6/x+5)
1.x+9/x+8- x+10/x+9=x+6/x+5- x+7/x+6;
