In the equation sqrt(a) + sqrt(b) + sqrt(c) + sqrt(d) + sqrt(e) = sqrt(f), each variable a distinct positive integer. What is the least possible value for f ?
Well, how about: sqrt(4) + sqrt(9) + sqrt(16) + sqrt(25) + sqrt(36) =sqrt(400) !.
+36915 How about:
sqrt(1) + sqr(4) + sqrt(9) + sqrt (16) + sqrt(25) = sqrt (225)
+2862 Basically just go up by perfect squares,
in other words, list the first 6 perfect squares, and the answer should be right in front of you
