In mathematics we might have come across different types of numbers like even, odd, prime, composite etc. But there is a special type of number i.e. perfect square. These can be identified and expressed by factoring the number.

Definition of perfect squares

In other words, it is defined as the product of some integer with itself.

How many perfect squares are there between 1 and 100?

There are eight perfect squares between 1 and 100 (ie excluding 1 and 100).

They are 4, 9, 16, 25, 36, 49, 64 and 81.

However, there are ten perfect squares from 1 to 10. They are 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100.

There are 30 perfect squares between 1 and 1000. They are 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 3124, 303, 441, 484, 529, 576, 625, 676, 729, 784, 841, 900 and 961.

Is 216 a perfect square?

A number is a perfect square or square number if its square root is an integer, which means it is the product of the integer with itself. As we know, the square root of 216 is approximately equal to 14.697.An integer that can be expressed as the square of another integer is called a perfect square So it is clear that 216 is not a perfect square number.
