There is only one number of this type which is
7744=88^2 where a is 7 and b is 4
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.

There are 8: the squares of 2 to 9, inclusive.

10 perfect squares
Two. 36, and 49 are perfect squares.
sqrt(2000) = 44.7sqrt(20000) = 141.4So the perfect squares between 2000 and 20000 are the squares of 45 to 141 (inclusive)ie there are 97 perfect squares in the interval.
To find the perfect squares between 20 and 150, we need to determine the perfect squares less than 20 and the perfect squares greater than 150. The perfect squares less than 20 are 1, 4, 9, and 16. The perfect squares greater than 150 are 169 and 196. Therefore, there are 5 perfect squares between 20 and 150: 25, 36, 49, 64, and 81.

No. There are infinitely many perfect squares so there is no "the" perfect square.
68 of them.
Eight of them.
