Suppose a quantity x can be dimensionally represented in terms of M, L and T, that is, [x] = Ma Lb Tc . The quantity mass

[X] = MaLbTc


[M] = [x.L-b.T-c]


now if a =0 then the solution (and the power) will be infinite. thus, then cannot be the exact dimension of the mass.


a ≠ 0 can't be considered


thus, the mass can be represented in term of L, T and X only when a ≠ 0
