Question 149455
how do you find the number that is not the square of an integer? 
----------------
What?? Most numbers are not the square of an integer. If you square the integers you get 1,4,9,16,25,36,49 etc.  All the numbers in between are not the square of an integer.
Between 9 and 16, there's 10,11, 11.7, 11.71, 11.7001, etc. There's an infinite number of them.
