For questions 1-2, simplify each expression.
1. 9!

a. 45
b. 362,880*
c. 265,456
d. 125,936

2.35p3

a. 12,755
b. 14,290
c. 13,800*
d. 18.250

3. which expression would you use to figure out the number of ways you can arrange the letters in the word equation?

a. 8!
b. 8p4*
c. 4p8
d. 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
