Answer 4

echelon

Answer 5

can please explain more please

Answer 6

1 x y
0 1 z
0 0 1
convert to this form by row and column operations and count the number of non-zero rows which in this case is 3 is the rank

Answer 7

what about the column

Answer 8

are u there?

Answer 9

yes m here

Answer 10

what ur question, not clear to me

Answer 11

in the of 4by 4 matrix how to determine the rank

Answer 12

rank of this matrix is 3

Answer 13

rank is found the same for any order square matrix

Answer 14

but what about 3by 3 matrix

Answer 15

u know row and column operations?

Answer 16

yes
what next

Answer 17

change the matrix to the form
1 a b
0 1 c
0 0 1
and count how many non-zero rows are there that will be the rank

Answer 18

u try ur and tell me

Answer 19

3

Answer 20

am i right

Answer 21

correct, same procedure for all other

Answer 22

Answer 23

yes the numbers of non-zero rows in that form i told, it is called Echelon form

Answer 24

now am geting u now

Answer 25

what about the collum

Answer 26

are u there?

Answer 27

i was a little far, now here, tell me

Answer 28

Answer 31

did u get it now

Answer 32

ok give example of 4by4 matrix
