If (2 to the x) - (2 to the (x-2)) = 3 (2 to the 12), what is the value of x?
Choose the correct choice from the following:  A) 9  B) 11  C) 13  D) 15  E) 14

Rationale: i am guessing the question is : ( 2 to the power x ) - ( 2 to the power ( x - 2 ) ) = 3 ( 2 to the power 12 ) 2 ^ x - 2 ^ ( x - 2 ) = 3 . 2 ^ 12 hence x = 14 . answer is e
Answer: E
