X(1/100+25/100)=1500方程怎么解
X(1/100+25/100)=1500方程怎么解
X(1/100+25/100)=1500方程怎么解
解26/100X=1500
X=1500/26%
X=1500* 0.26
X=390
x=75000/13
摆脱楼上的,算完验证一下好不?390……带入原式最后答案是101.4
26/100X=1500
x=1500 * 100/26
x=150000/26
x=75000/13
(X+X)+(X-X)+(X*X)+(X/X)=100
x-2x+3x-4x+5x.+99x-100x=25求解
100^1/x=25求x,
1/2x+1=1/2-1/3x x-2x+3x-4x+...+99x-100x=25解方程
x-2=(104-x)+2 6x-59=10x-75 (x+10)+(x-15)=280-x4(x-62)=x-38 60x-40=(60+20)*(x-5) 32x+32*0.5-25x+64x=24x+496-49x x+15=3*(109-x ) 5(3x-1.4)=2(6x-0.5) 3(x+0.9)=5(x-1.7) 13x-4(2x+5)=17(x-2)-4(2x-1) (13x+8)/3=5x-1x-60=2[(3561-x)+100]+1 (x+9)+12=2[(x-9)-1
1/X(X+1)+1/(X+1)(X+2)+1/(X+2)(X+3).+1/(X+99)(X+100)=
解方程:x-2x+3x-4x+...+99x-100x=25
解方程:x-2x+3x-4x+.+99x-100x=25
x-2x+3x-4x+...+99x-100x=25
设函数f(x)=(x-1)(x-2)...(x-100)(x>100),求F'(X)
f(x)=x(x-1)(x-2)…(x-99)(x-100),求f'(100)
解方程:2x+4x+6x...+100x=1-(x+3x+5x+...+99x)
1X+2X+3X…+98X+99X+100X=50500X X等于多少?
1x+2x+3x+4x+5x+6x+7x…+99x=100
x除55%=100 60%x=30 x+50%x=4.5 (1-25%)x=72 4x+40%x=176 解方程
怎样计算百分数的方程120-25%x=100x+13%x-28%x=3.4(1-40%)x=720x-95%x=155
X+25%X+15%X=420 2X+150=20501.5X-1200=(1+20%)2X-5+X=100
已知x^4+x^3+x^3+x^2+x^1+1=0,求x^100+x^99+x^98+x^97+x^96的值
