己知|a-2l+lb-3i+|c+1l=0.求下列各式的值:(1)a-b-c.la+b|-丨c|

己知|a-2l+lb-3i+|c+1l=0.求下列各式的值:(1)a-b-c.la+b|-丨c| 己知|a-2l+lb-3l+lc-4l=0,求式子a+b+c的值 己知|a+2l+lb-1|=o,则(a+b)^2008的值是 la+3l+lb-2l+c+1l=0求a+b+c 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. 已知Ia-2I+lb-3I+Ic-4l=0求a+b-c的值 已知la+1l+lb+2I+丨C+3I=0求(a-1)(b+2)(C-3)的值 如果有理数a.b.c满足la-1l+lb+3l+l3c-1l=0,(abc)^125/(a^9b^3c^2)的值. 已知la-2l+lb-3l+lc-4l=0,求a+2b+3c的值 已知la-2l+lb+3l+lc-4l=0,求a+2lbl+3c的值? la-2l+lb-3l+lc-4l=0,求式子a+b+c的值. 如果la-1l=1,lb-2l=3,则a+b= (a-2)^2+lb+3l=0 已知|3-2a|+lb+1/3l=0求a,b的值 已知实数a,b,c满足la-1l+lb+3l+l3c-1l=0,求(axbxc)^2007的值 若la+2l+lb+3l=0,则3a+2b= la-1l+lb+3l=0求b-a-0.5的值
