What is square root????

Dear Student,
When a number is multiplied by itself, the product obtained is known as the square of the number multiplied. The number which is initially multiplied is known as the square root of the product obtained. 
​​​​​​For eg: When 2 is multiplied by itself, that is 2, the product obtained is 4. 
Here, 4 is the square of 2 and, 2 is the square root of 4. 
Similarly, 3 is the square root of 9, 
4 is the square root of 16 and so on. 
Regards
