A number AABB is the square of an integer. Find this integer, aided by pen and paper. No other calculating aids allowed.
7744 is the only such number. (Charlie proved that)
No number of the form AABB is a 3rd, 4rth, 5th, 6th, 7th, 8th, 9th, 10th, 11th, 12th or 13th root. No number of the form AAABBB or AAAABBBB is an nth root, wher 2 <= n <= 20.
Is there anything else you don't need to know ?
