Explain how 2 x 10-4 is the same as 2 ÷ 104 using expanded notation.

because the fractions i doid this in november

Step-by-step explanation:

a=r

d=q

c=p

b=s

hope this !

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
