A number, containing no zeros, changed to 510,000 after it was rounded. To what place was the number rounded? Complete the explanation.
The number was rounded to the (blank) place. All the digits to the right of the (blank) place are (blank)

36 is the final answer! : )

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
