Yes, a perfect square is a number that has an integer square root.
No, 3.6 is not a perfect square. A perfect square is defined as a number that has a whole number for a square root. In other words, there's no whole number that, when multiplied by itself, equals 3.6.
No, a perfect square number will ALWAYS ends in 0,1,4,5,6,9
Sometimes the square root of a positive number can be irrational, as in the square root of 2 (which is a non-perfect square number), but sometimes it is a rational number, as in the square root of 25 (which is a perfect square number).
A perfect square is a whole number multiplied by itself. 121 = 11*11
Then the number is called a "perfect square".Then the number is called a "perfect square".Then the number is called a "perfect square".Then the number is called a "perfect square".
No, there aren't any square numbers between 70 and 80. From 70 to 80, no number has a perfect square root, so no square number exists between 70 to 80.
80
NO!!! As it is 80 X 8 However, 6400 is a perfect square as 80 X 80
For a number to be a perfect square, the number's square root has to be a whole number. 9 is a perfect square because its square root is a whole number, 3. If the square root of the number is a decimal, then it is not a perfect square. For example, 13 does not divide evenly so it not a perfect square.
Infinitely many, since every number in that range is a square of some other number. There are 7 perfect square numbers.
If by 'perfect number' you mean 'perfect SQUARE', then yes. 49 is an odd number and a perfect square.
There is not a number that is a perfect square and perfect cube between 1 and 25.There is not a number that is a perfect square and perfect cube between 1 and 25.There is not a number that is a perfect square and perfect cube between 1 and 25.There is not a number that is a perfect square and perfect cube between 1 and 25.
20 is a not perfect square.
yes. the square root of 6400 is 80.
You take the square root of the number. If it is a perfect square, this will be a whole number. If it is not, it isn't a perfect square.
It is the definition of a perfect square.
