How many numbers lie between 4square and 5square

Answer»

Between 4^2 and 5^2 if we look CAREFULLY there are INFINITE numbers like 4 square is 16 so there are 16.1,16.22 ,16.77777.......and so on continue....but if we are TALKING about just integers then there are 9 numbers...and we INCLUDE 16 and 25 so there are 11 numbers.....
