aeroO bics 2^n is used for finding no of subsets not no. Of elements in a normal set...but since subsets are the elements of a power set therefore 2^n gives us the no. Of elements only in power sets ...so we need to keep in mind that if eg we have (1,2)
Its subsets are ((1),(2),(1,2),null set).so the formula applies here 2^n ..here n=2 therefore total subsets =4 and so are the total elements of the required power set

Good work
You cleared my confusion regarding subsets...
please add more videos, your videos are good
But in the case where you take the power set of the set containing 1 and 2 you have only 3 elements(0, 1, 2) and not 2^2 elements?
