Question 781328: Assuming he lives that long, one author of our book, Hornsby, will be 76 years old in the year x^2 (X is a counting number). In what year was he born? Answer by Edwin McCravy(20056) (Show Source):
The square root of this year 2013 is 44.86646855, so
the next perfect square year will be 45² or 2025.
So if he is 76 in 2025, he was born 76 years before
2025, so he was born in 2025-76 or 1949.
