The Fifteenth Amendment to the United States Constitution was passed on February 3, 1870.
The answer is 14,348,907. There was an answer "375" here before, which I can only assume is a mistake for fifteen to the third power--that is 3375. Three to the fifteenth power means 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3.
