Match each binomial expression with the set of coefficients of the terms obtained by expanding the expression (2x+y)^4, (x+2y)^4, (x+3y)^4, (3x+2y)^4

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
