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

Find the rank of matrix [ [1,1,-3,2],[2,-1,2,-3],[3,-2,1,-4],[-4,1,-3,1] ]

Find A if [[1,0,-1],[-2,-1,4],[-1,0,2]]A = [[-1,-2,2],[3,4,-3],[3,4,-1]]

4) find the rank of [[1,-3,1,2],[0,1,2,3],[3,4,1,-2]]

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=[[1,2,3],[3,-2,1],[4,2,1]] A^-1

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.

Let A={1,2,3,4} and R be a relation in given by R=(1,1),(2,2),(3.3).(4,4),(1,2),(2,1),(3,1),(1,3)} Then R is

Given below is the data showing the number of children in a family, in a locality of 15 families. 1,3,5,4,3,2,1,1,3,2,2,1,4,2 and 1. and Draw the frequency table to represent the data.

Let A={1,2,3,4} and R be a relation in given by R= (1,1), (2, 2), (3. 3). (4,4), (1,2), (2,1),(3,1), (1,3)} . Then R is
