Hello dear student,

Before answering your question let me brief you about square root .

√x = y

This y is called as square root ,√ is called radical sign or radix.

Now let's come to your question here x = 900 so in order to determine it's square root firstly we need to do prime factorization .

900. = 2× 2× 3× 3× 5× 5

Here 900 is a perfect square because it's prime factors can be expressed in pairs.

So ,√900= 30

Thus 30 is square root of 900.

I hope this helps

Hello Charan,

The answer to your  question is nothing but 30. use a calculator or basic method of factorisation to find the sqaure root of any given number.
