How many positive integers less than 2008 have an even number of divisors?
There are 1,963 such integers. Every factor of a number has a pair. The only time there will be an odd number of factors is if one factor is repeated, ie the number is a perfect square. So the question is really asking: how many positive integers less than 2008 (in the range 1 to 2007) are not perfect squares. √2007 = 44 and a bit (it lies between 44 and 45) So there are 44 integers less than (or equal to) 2007 which are perfect squares → 2007 - 44 = 1963 integers are not perfect squares in the range 1-2007 and have an even number of factors (divisors).

How do you estimate a square root that is not a perfect square yet?
Find the perfect squares that your number lies between. Your square root will lie between their square roots. Whichever it is closer to will indicate the size of the decimal.
Why is 128 a square number?
no- 121 is the square of 11 and 144 is the square of 12 and there are no squares in between but that is where 128 lies .

Why is 63 not a square answer?
It can be, only it is not a perfect square. 72 = 7*7 = 49 and 82 = 8*8 = 64 So 63 lies between the squares of 7 and 8 and so there is no whole number whose square is 63.
64 square must lie between what two one decimal place?
Square root of 65 lies between 8.0 and 8.1. Explanation: Squares of natural numbers are {1,4,9,16,25,36,49,64,81,...}, which are squares of {1,2,3,4,5,6,7,8,9,....} As 65 lies between 64 and 81, square root of 65 lies between 8 and 9 Further, 8.12 = 65.61 and as 8.02 = 64, square root of 65 lies between 8.0 and 8.1.
Why is 50 not a perfect square?
A perfect square has the condition that it must be any positive integer multiplied by itself. The closest perfect squares to 50 are 7*7 = 72 = 49 and 8*8 = 82 = 64 since 50 lies between 49 and 64, it must be it is not the square of a positive integer and, therefore, is not a perfect square.
