How can you tell by looking at the prime factors of 17640 that the square root of 17640 is not a whole number?
Write the prime factors as powers. In a square number, each prime number appears an even number of times - i.e., an even power. Examples: 4 = 22 (even power, this is a square) 144 = 24 x 32 (all powers are even, this is a square) 12 = 22 x 3 or 22 x 31 (3 has an odd power so it is not a square) (If a number is a perfect square, that is equivalent to saying that its square root is a whole number.) * * * * * In this case there is a particularly fast method. The number ends in 0 so 10 must be a factor of the number. That is to say, 2 and 5 must be prime factors of the number. If it is a square then 22 and 52 must be factors of the number ie 22 x 52 = 100 must be a factor. But if 100 is a factor, the number must end in 00. It does not so it cannot be a square.
You are thinking of a number it is between 1 and 100 it is a square number it has 32 as a factor is even it has two digits what number you are you?
64

Choose a counting number square it then add the original number the result will always be even?
Square of any even counting number is always an even number and square of any odd number is always odd. Addition of even number and its square is always an even number because even + even results in even number and addition of odd number and its square is always an even number because odd + odd = even number. Since natural or counting numbers consists of only even and odd, which comes one by one after each other. So, according to the question and the given condition only one answer comes out which is an even number. e.g. let us take the counting number like 8, square of 8 = 82 =64 and addition of 8 and its square =8+64 =72 which is an even number.
