Answer:
100
Step-by-step explanation:
The perfect square integers are:
1^2 , 2^2, 3^2, 4^2, 5^2, 6^2, ...
1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, ...
We note from the list above that the smallest integer
whose square root is an integer of two digits is 100.
The next smallest perfect square is 81, and its square
root is 9, which is a one digit integer.
