If a and b are positive numbers, and a^3 + b^3 = 140, then the greatest possible value of a is between: Select
A) 0 and 2 B) 2 and 3 C) 3 and 4 D) 4 and 5 E) 5 and 8
If a = 5.1 and b is a bit less than 2, then a^3 + b^3 can equal 140.   If a &gt; 8, then a^3 + b^3 &gt; 140.   The answer is 5 and 8.
