简便运算、定义新运算.简便:1、7.48+3.17 - (2.48 - 6083)2、8.75 - 0.35+(1.25 - 6.65)3、7.6*1.75+17.5*0.24定义新运算:a☆b=a+b - 1,a○b=a*b - 1求:若x☆(x○4)... -
17846宗琼
：[答案] 1、6083应该为6.83 7.48+3.17-(2.48-6.83) =7.48-2.48+3.17+6.83 =5+10 =15 2、8.75-0.35+(1.25-6.65) =8.75+1.25-(0.35+6.65) =10-7 =3 3、7.6*1.75+17.5*0.24 =7.6*1.75+1.75*2.4 =1.75*(7.6+2.4) =1.75*10 =17.5 x☆(x○4)=x☆(4x-1)=x+4x-1-1=5x-2=...

设三阶方阵满足a - 1ba=6a+ba,且a= 求b设三阶方阵A、B满足关系式A - 1BA=6A+BA,其中 A=下图求矩阵A.a - 1ba=6a+ba,为a^ba=6a+ba -
17846宗琼
：[答案] A^(-1)BA=6A+BA 则(A^(-1)-E)BA=6A 因为A 显然为非奇异矩阵.等式左右 右乘A^(-1) (A^(-1)-E)BA*A^(-1)=6A*A^(-1) (A^(-1)-E)B=6E 则:B=6(A^(-1)-E)^(-1) 由A得 A^(-1)= 3 0 0 0 4 0 0 0 7 (A^(-1)-E)= 2 0 0 0 3 0 0 0 6 则(A^(-1)-E)^(-1)= ...

线性代数,求大神帮忙~设abc均为n阶矩阵,E为单位矩阵,若B=E+AB,C=A+CA,则B - C=要详细步骤,谢谢啦~ -
17846宗琼
：[答案] B = E+AB , (E-A)B = E, 则 E-A, B 均可逆,B = (E-A)^(-1), E-A = B^(-1); C = A+CA, C(E-A) = A, CB^(-1) = A, C = AB 得 B-C = B-AB = E

设A、B均为n阶方阵,I为n阶单位矩阵,若A+B=AB,求证AB=BA -
17846宗琼
：[答案] A+B=AB,所以(A-I)(B-I)=I,说明A-I与B-I互为逆矩阵,设它们为X,Y, 即A=I+X,B=I+Y,X与Y互逆, 所以,AB=(I+X)(I+Y)=I+X+Y+XY=2I+X+Y, BA=(I+Y)(I+X)=2I+X+Y, AB=BA
