To start you off here's a hint: 144 = 122...
The perfect squares less than 101 are: 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100.
Perfect squares have odd numbers of factors. The perfect squares less than 100 are: 1,4,9,16,25,36,49,64,81,100. 64 seems to fit both criteria.
Answer: 1, 64, & 729
1, 4, 9, 16 and 25.
1
26 of them, starting with 29² up to 54².

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.
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.
