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.
There is no pair of perfect squares that sums to 21. And the question is pointless if it is not about perfect squares because in that case there are infinitely many answers.There is no pair of perfect squares that sums to 21.

There are no four-digit perfect squares that are palindromes.
None. √1976 is "44 and a bit" → first perfect square ≥ 1976 is 452 = 2025 As 1976 is not a perfect square and the first perfect square greater than 1976 is 2025, and 2025 is greater than 2013, there are no perfect squares from 1976 to 2013.
There are three perfect squares between 0 and 50 that are even.

26 of them, starting with 29² up to 54².
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.
Perfect squares have an odd number of factors. There are 31 perfect squares less than 1000.

683 perfect squares.
10 perfect squares
There are 8 perfect squares TTThe
There are no four-digit perfect squares that are palindromes.
99, because 100 squared is 10000 and since it has to be less than 10000, it is 99.
Two. 36, and 49 are perfect squares.
