यदि `|{:(1,0,1),(0,1,2),(0,0,4):}|` दर्शाइये कि - `|3A|=27|A|`.

If A=[[1,0,1],[0,1,2],[0,0,4]] then show that |3A|=27|A|

If A=|[1,0,1],[0,1,2],[0,0,4]| then |3A|

If A=|{:(1,0,0),(0,1,0),(0,0,1):}|" and A"=[{:(0,-3,4),(1,2,3),(0,5,5):}]," then find "(I-A)^(-1)

If A=[[1 ,0 ,1],[0 ,1, 2],[ 0, 0, 4]] , then show that |3A|" "=" "27|A|

If A={:[(3,2,7),(1,1,4),(-1,-1,0)]:},B={:[(1,0,3),(2,1,0),(0,-1,-3)]:}andC{:[(1,0,0),(0,1,0),(0,0,1)]:} , then find 2A+3B-7C.

A= [{:( 1,0,0) ,( 0,1,1) , ( 0,-2,4) :}] ,I= [{:( 1,0,0) ,( 0,1,0),( 0,0,1) :}]and A^(-1) =[(1)/(6) (A^(2)+cA +dt)] then , the value of c and d are

Evalute the determinants in queations 1 and 2 : If A=|{:(1,0,1),(0,1,2),(0,0,4):}|
