(a) If `A=[[2,5], [1,3]]` then find `A^-1`

(2) If A=[[2,3],[1,5]] then find A^(-1)

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

If A=[[2,a,-3] , [0,2,5] , [1,1,3]] then,find the value of a for which A^(-1) exists.

If A=[[1,2,-3] , [5,0,2] , [1,-1,1]] and B=[[3,-1,2] , [4,2,5] , [2,0,3]] then find matrix C such that A+2C=B

If A=[2,3,5] and B=[[1],[2],[3]] , find AB

Evaluate the following: If A=[[1,1,-2],[2,1,-3],[5,4,-9]] find |A|

if, |A| = [[2,3],[1,5]] find the minors.

If A=|{:(3,5),(2,4):}| , find A^(-1) .

If A= [(1,1,3),(5,2,6),(-2,-1,-3)] then find A^(14)+3A-2I
