can somebody plz find a value or show me how to find a value for x such tht,
where x and n are integers
or otherwise prove tht for no integeral value of x can be an integeral multiple of 3.
Not sure what class you are in exactly, but
Now, if x and n are integers, then 2^x and 3n are integers.
So look at the prime factorization of both sides. Clearly the prime factorization of the RHS contains a 3, but the prime factorization of the LHS contains only 2s. Thus the two sides cannot be equal for x and n integers.
