Answer 1

Answer #1

LL Given , B and D are invertible matrices. of order n and p respectively. (6 8). then order of Ais nep. B and D are invertib

so B exists Januar / Since B is invertible and 8x = 0 → B(Bx) = 340 = 0 Tue X = 0 • from CX + DZ = DZ Again CW + DY Y = - D

So, ཡི A - (9 (༧ x Y 2 at ཉྩ༤/ o -DCB (And? ལ་ 79f རྒྱ་
