Some perfect squares (such as 100), have a digit sum ($1+0+0 = 1$) that is equal to the digit sum of their square root ($1+0 =1$). Some other perfect squares (such as 121), have a digit sum ($1+2+1 = 4$) that is equal to the square of the digit sum of their square root ($(1+1)^2 = 4$). What is the smallest perfect square greater than 100 that is in neither of these two categories?

 

DO not give answer let me also do some math to get the answer

I couldn't think of a way but guessing and checking. HOWEVER, it won't take long to guess and check. cheeky
