103
Step-by-step e103xplanation:
Perfect square less than 8939. It is between 90 and 100 as first 2 digits of given number - 89 is a number between 81 and 100.
Lets try 95^2. It is = 1025 so greater than given number.
Next, 94^2=(95-1)^2=1025-2*95+1=8836, which is smaller than given and is the number we are looking for.
8939-8836=103 is the answer
