[[-1,-2,3],[-2,2,1],[4,-5,2]]

Find A and B where 2A+B= [[2,2,5],[5,4,3],[1,1,4]]"and" A-2B=[[1,6,5],[5,2,-1],[-2,-2,2]]

Answer the following questions.Find x,y,zif {[[1,3,2],[2,0,1],[3,1,2]]+2[[3,0,2],[1,4,5],[2,1,0]]}[[1],[2],[3]]=[[x],[y],[z]]

Delta=abs([1xx5,2xx5,3xx5],[3,1,6],[4,2,1]) =5 abs([1,2,3],[3,1,6],[4,2,1])

If A = [(2,2,1), (1,3,1), (1,2,2)] then A^-1+(A-5I) (AI)^2 = (i) 1/ 5 [[4,2, -1], [-1,3,1], [-1,2,4]] (ii) 1/5 [[4, -2, -1], [-1, 3, -1], [-1, -2,4]] (iii) 1/3 [[4,2, -1], [-1,3,1], [-1,2,4]] (iv) 1/3 [[4, -2, -1], [-1,3, -1], [-1, -2,4]]

A=[[2,3],[4,5],[2,1]] B=[[1,-2,3],[-4,2,5]] Find AB

If A=[(1,-2,3),(-4,2,5)],B=[(1,3),(-1,0),(2,4)] then 2A+3B'=

If A=[(1,-2,3),(-4,2,5)],B=[(2,3),(4,5),(2,1)] then

If A^(-1)=(1)/(3)[[1, 4, -2], [-2, -5, 4], [1, -2, 1]] and |A|=3 , then adjA=

Construct a frequency table for the following: 3,2,5,4,1,3,2,2,5,3,1,2,1,1,2,2,3,4,5,3,1,2,3.
