For each expression, combine like terms and write an equivalent expression with fewer terms.
a. 4.2 +32
b. 3.x +5x-1
c. 5+2+7+4.0
d. 4- 2x + 5.0
e. 10. - 5+ 3.1 -- 2

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
