step-by-step explanation:

step-by-step explanation:

i believe what you're asking is how do you post on it is quite simple all you would have to do is click "post question button", select a subject that you need with then just wait for a user to reply. is powered by users which means there's a chance of human error which means sometimes people will get the answer wrong. usually the higher they are ranked on this platform the higher probability which they got the steps correct. if you still need see there q& a.

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
