" 9.(i) यदि "|[3,1,-4],[3,2,5],[1,-1,3]|=49" हो,तो "|[6,3,-10],[6,6,20],[2,-3,12]|" はा मान बताओ "

If |[3,1,-4] , [3,2,5] , [1,-1,3]|=49 then |[6,3,-16] , [6,6,20] , [2,-3,12]|=

if |{:(3,1,-4),(3,2,5),(1,-1,3):}|=49 , then evaluate |{:(6,3,-8/3),(6,6,10/3),(2,-3,2):}| .

if |{:(3,1,-4),(3,2,5),(1,-1,3):}|=49 , then evaluate |{:(6,3,-8/3),(6,6,10/3),(2,-3,2):}| .

If A=[[3, 5, -1], [2, 0, 4], [1,-3, 0]] , then [[12, 4, -6], [3, 1, 14], [20, -14, -10]] is

Let A=[[3,6,5],[6,7,8]] and C=[[1,2,-3],[4,5,6]] Find 2A

If ,A = [(1,2),(-2,4)] ,then -3A= [(-3,-6),(6,-12)]

(2) Find the rank of the matrix A=[[1,2,3,-1],[3,6,9,-3],[2,4,6,-2]]

Wherever possible write each of the following as a single matrix. (i) [{:(,1,2),(,3,4):}]+[{:(,-1,-2),(,1,-7):}] (ii) [{:(,2,3,4),(,5,6,7):}]-[{:(,0,2,3),(,6,-1,0):}] (iii) [{:(,0,1,2),(,4,6,7):}]+[{:(,3,4),(,6,8):}]

If A=[[-1,2],[1,-1]] then, A^(3)-6A^(2)+10A-I=?

If Delta = |{:(1,2,3),(2,3,5),(3,6,12):}|and Delta' = |{:(4,8,15),(3,6,12),(2,3,5):}| , then
