The perfect squares that are less than 20 are 0, 1, 4, 9, and 16.
Any number squared except 0 is a perfect square so it follows that prime numbers are less common than perfect squares.
1, 4, 9, 16, 25, 36, 49
99, because 100 squared is 10000 and since it has to be less than 10000, it is 99.
11 x 11 = 121 12 x 12 = 144 13 x 13 = 169 14 x 14 = 196

The perfect squares that are less than 20 are 0, 1, 4, 9, and 16.
To start you off here's a hint: 144 = 122...
Integers which are the squares of integers are called perfect squares or square numbers. Perfect squares less than 101 are 1, 4, 9, 16, 25, 36, 49, 64, 81 and 100.
The only squares of perfect squares in that range are 1, 16, and 81.
7^2=49 < 50 < 8^2=64 < 9^2=81 < 10^2=100 < 110 < 11^2=121 so there are 3 perfect squares greater than 50 and less than 100 viz. 64, 81 and 100.
The perfect squares less than 101 are: 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100.
Any number squared except 0 is a perfect square so it follows that prime numbers are less common than perfect squares.

Perfect squares have an odd number of factors. There are 31 perfect squares less than 1000.
The perfect squares less than 101 are: 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100
