Note that "-" in the question is an operator, but NOT the sign of subtraction as general use.
To avoid confusion, I rather use another sign "#" instead of "-".
5 # 4 = 5² - √4 = 23
8 # 1 = 8² - √1 = 63
6 # 16 = 6² - √16 = 32
9 # 9 = 9² - √9 = 78
3 # 9 = 3² - √3 = 6
3 # 81 = 3² - √81 = 0
The answer = 0
