求齐次线性方程组 (1)A-8B+10C+2D=0 2A+4B+5C-D=0 3A+8B+6C-2D=0 (2) A+B
a,b,c,d为三维列向量A=[a,2c,3d]B=[b,5c,d].且|A|=-12,|B|=15,求|A-B|
若a-b=-3,c+d=2,则(b+c)-(a-d)的值( ) a.-1 b.-5 c.5 d.1
若a-b=-3,c-d=2,则(b+c)-(a-d)的值( ) a.-1 b.-5 c.5 d.1
A×2=a B×4=b C×6=c D×12=d A+B+C+D=256 a+b+c+d=770 求A·B`C`D和a`
数学解方程,复杂啊-12=3a+2b+c ①0=-a+b-c+d②0=27a+9b+3c+d③1=a+b+c+d④帮忙解
