600x=450(x+100)600x=450(x+100)600x=450(x+100)600x-450x=45000x=300600x=450x+45000150x=45000x=300600X=
600x=450(x+100)
600x=450(x+100)
600x=450(x+100)
600x-450x=45000 x=300
600x=450x+45000
150x=45000
x=300
600X=450X+450×100 150X=45000 X=45000÷150 =300
600x=450(x+100)
(X+X)+(X-X)+(X*X)+(X/X)=100
(x+x)+(x-x)+(x/x)=11.2
(2x•x+x•x+2x•x)•2+x•x•6+2x•x•4=600
X+X+X+X+X+X+100X=1690 问:X等于多少
(x+1)X百分之三十+(100-X)X百分之二十五=2/5X
x*x*x*x+2008x*x+2007x+2008(提示:x*x*x-1=(x-1)*(x*x+x+1))
600-25X+100X-5X^2=840
(100-x)/x=25% 求x怎么算?
(X/80+X/100 +5)*40=X,
2X/(X/80+X/100)=
(X-30)/X=45/100 求X
100x=50(600-x)等于多少
x(100-2x)=600
若1+x+x*x+x*x*x=0,求x+x*x+x*x*x+.+x(2000次幂)
已知:f(x)=x(x-1)(x-2)(x-3)……(x-100),求f'(5)
X(1+20%)=X+600 =120%X=X+600 = X(1+20%)=X+600 =120%X=X+600 =
80(X+2)=100X
