Find the perfect square numbers between (i) 30 and 40 and (ii) 50 and 60.
Since, 1 x 1 = 1
2 x 2 = 4
3 x 3 = 9
4 x 4 = 16
5 x 5 = 25
6 x 6 = 36
7 x 7 = 49
Thus, 36 is a perfact square number between 30 and 40.
Since, 7 x 7 = 49 and 8 x 8 = 64. it mean there is no perfect number between 49 and 64, and thus there is not perfect number between 50 and 60.
