Can someone help me understand this...
Or simplify it:
How does such a seemingly odd string of irrational numbers equate to exactly 142?
Better yet how would someone have come up with this  mathematically; not via trial and error?
Interestingly, the first half is almost exactly twice the second half.
(√√7! + √√7!) * (√(√7! + (√7!)/7!)) = 142
Thanks
