Find the number of three-element sets of distinct positive integers {a, b, c} such that abc = 210.
Let a, b and c be three positive real numbers such that the sum of any two exceeds the third and abc > 1. The expression logx(a + b – c) + logx(b + c – a) + logx(a + c – b), where x > 1, cannot exceed
Options:
1. (1/2)*logx abc
2. logx abc
3. (2/3)*logx abc
4. (4/5)*logx abc
