若la-b+3l+(2a+b)^2=0,化简2a^3b(2ab+1)-a^2(-2ab)^2
若la-b+3l+(2a+b)^2=0,化简2a^3b(2ab+1)-a^2(-2ab)^2
若la-b+3l+(2a+b)^2=0,化简2a^3b(2ab+1)-a^2(-2ab)^2
la-b+3l+(2a+b)^2=0
a-b+3=0
2a+b=0
解方程组得:
a=-1,b=2
2a^3b(2ab+1)-a^2(-2ab)^2
=4a^4b^2+2a^3b-4a^4b^2
=2a^3b
=2*(-1)^3*2
=-4
因为|a-b+3|>=0,(2a+b)²>=0
要使|a-b+3|+(2a+b)²=0
只能有a-b+3=0,2a+b=0
解这个二元一次方程组得a=-1,b=2
2a³b(2ab+1)-a²(-2ab)²
=4a^4b²+2a³b-4a^4b²
=2a³b
=2×(-1)³×2
=-4
la-b+3l+(2a+b)^2=0
因为绝对值和平方都应大于等于0
所以a-b+3=0
2a+b=0
所以a=-1,b=2
2a^3b(2ab+1)-a^2(-2ab)^2
=2a^3b(2ab+1)-a^2*4a^2b^2
=2a^3b[2ab+1-2ab]
=2a^3b
=2*(-1)^3*2
=-4
若la+2l+lb+3l=0,则3a+2b=
若la-5l+lb+6l=0,求-b-a-(-2/3)的值
若la+2l+(b-3)^2=0,则b^a=?
la+3l+lb-2l+c+1l=0求a+b+c
la+2b-9l+(3a-b+1)*2=0 a=?b=?
la+3l+lb-2l=0,求a的b次幂
已知la-3l+lb-5l=0,求5a-2b的值?
la-2l+(b+2/3)平方=0,则b的a次方=
已知la-2l+(b+3)²=0,则a+b=
若(a-6)的2次方+la-b+3l=0,则a+2b等于多少
如果la-2l+lb-3l=0,则2a+b分之a+b=
已知la-2l+lb-3l+lc-4l=0,求a+2b+3c的值
la-1/2l+lb-1/3l+lc-1/4l=0那么a+b-c=?
la-1/2l+lb-1/3l+lc-1/4l=0,求a+b+c的值.
la-2l+lb-3l+lc-4l=0,求式子a+b+c的值.
若la-3l+lb-7l=0,求a+b+2000的值
已知la-2l+lb-5l=0,求a和b的值.
la-1l+lb-2l=0,求a+b的值
