Given that x = 2^b – (8^35 + 16^5), which of the following values for b yields the lowest value for |x|?
Choose the correct choice.
A) 104
B) 105
C) 106
D) 107
E) 125
8^35 + 16^5 = 2^105 + 2^20   Compared to 2^105, the value of 2^20 is negligible.   2^105 - (2^105 +2^20) will minimize the value of |x|.   The answer is 105.
