A problem of power calculation The square of 2 + 2 + 2 + the cube of 2 + the fourth power of 2 +. + the power of 2006 =?

2 + 2 + 2 square + 2 cube + 2 quartic power +. + 2 2006 power = 2 + (2 + 2 square + 2 cube + 2 quartic power +. + 2 2006 power) in brackets is an equal ratio sequence of A1 = 2, q = 2, n = 2006, which is easy to do. Use the sum formula of equal ratio sequence Sn = A1 (1-Q ^ n) / (1-Q) = 2 + (2 * (1-2 ^ 2006) / (1
