I will mark Brainliest An example of a rational number is.

A. negative Start Root 16 End Root

B. Start Root 27 End Root

C. negative Start Root 2 End Root

D. Start Root 57 End Root

I think d. Sorry if I am wrong.

Step-by-step explanation:

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

answer is : muchas/tipicas

have a nice day!
