若2X+5Y=3,则4^x*32^Y=( ) 主要是32^y怎么等于2^5y
若2X+5Y=3,则4^x*32^Y=( ) 主要是32^y怎么等于2^5y
若2X+5Y=3,则4^x*32^Y=( ) 主要是32^y怎么等于2^5y
4^x*32^Y
=(2^2)^x * (2^5)^y
=2^2x*2^5y
=2^(2x+5y)
=2^3
=8
若5x+3y=3x+4y=x+2y+6,则x+y=___
若x/y=4/3 则3x+2y/2x-5y=
若3x-5y=0,则x+y/x=(),x-y/y=(),2x-3y/2x+3y=( )
若2x-3y+4=0则x(x*x-1)+x(5-x*x)-6y+7
若x+y=4,则多项式1/2(x+y)+4(x-y)-3(x-y)-3/2(x+y)-x+y值是()
若x-2y=5,则式子12-x+2y=.以知3x-4y=2x+y则x∶y=
若|2x-y+5|+(x+2y-4)的平方=0,则(2x-y)的三次方-(x-3y)(y-2x)的平方
3(x+y)+2(x-y)=36 4(x+y)-5(x-y)=2
若(x-y)/(x+y)=3 则(x+2y)/(6x-7y)等于
4(x-y)-3(x-y)=9 5(x-y)+2(x-y)=11
3(x+y)-4(x-y)=11,2(x-y)+5(x+y)=27
先化简再求值(x-y)(x-2y)+(x-2y)(x-3y)-2(x-3y)(x-4y) x=4 y=5
若(x*x+y*y)(x*x+y*y)-4x*x*y*y=0,求代数式(x*x+5xy+y*y)/(x*x+2xy+y*y)的值
(5)若x/2=y/3(y不为0)则x/y=____,x+y/y=___,y/x-y=___.
已知x*x+4x+y*y-2y+5=0,则x*x+y*y=?
若x/2=y/3=z/4则3x-2y+5z/x+y+x=
若2x=3y,则(x*x+y*y)/x*x=?
