     (0 -2 6 2)
    (-2 4 9 -1)

a). size of E=

b) element e23=

c) Designate symbolically the number 4 in the matrix:

d) find the E inverse:

Solution

a) size of E is 3 x 4

b)element e23 is 6

c)number 4 is e32

d)Non-square matrices do not have inverses.E is not a square matrix so E doesnot have inverse
