Dimension of a x b can be calculated by getting dimensions of a and b individually
To get the dimension of 'b', get the dimension of 'power'
and to get the dimension of 'a', i.e. a = x^2/pt, and get its dimension
b. For diesnion consistency of the relation, check LH terms and similarly for RH terms..
if same, then they are consistent otherwise not..
