Problem 14 from prior weeks.
Correct!
Explanation:
Solution: 49 comes next. This is the series of integers who digits' products are positive perfect squares. So 11's digits multiplied are 1 x 1 = 1, a perfect square; 14's are 1 x 4 = 4; so the next number after 44 whose digits multiply to a perfect square is 49 (4 x 9 = 36).
