Do you where has gone wrong?

  1. you are supposed to multiply the cube of m by 2 [ 2m^3 ] and to do that the steps that should be carried out are :

    m x m x m = m^3
    2 x m^3 = correct expression :D

    but the expression in the algebraic notation suggests that you find the cube of 2 times of m [ (2m)^3 ] and that suggests that the steps that should be carried out are :

    2 x m = 2m
    2m x 2m x 2m = wrong ans :|

    [ both are COMPLETELY different ]
