solving for the dimension of a complicated formula has been always a tough task aomong the student community,

and the situation get worse if u hav  the time constraint but,

DON'T WORRY v r here to give the proper technique for these type of probs,

LOOK, ......... der some short tricks by which u can make yr lie easy such :

if formula hav hc/lamda then consider the whole thing together & remember its dimension is that of energy (ML^2t^-2),
 similarly v*i hav power dimension, u have search these type of terms if not exactly present then make some manipulations by multiplying or dividing by some known thing,

 remember( mu*epsilon = c^2   dimension = M^2T^-2 ) for the time being learn to manipulate smwat,
even if u face any prob then u can pist specific prob i wud elaborate the trick  in more detail.
