# Square root in just 5 second

**How we can find the squre root of number whose last digit is '5' ?**

##### Find square root **'1455'**

### STEP 1 :

First we will split the given square root from the last digit which is '5'.

like this :

##### VALUE ONE : **145** and VALUE TWO : **5**

### STEP 2 :

Now we will take VALUE ONE and Multiply it with its successor value like given below:

##### VALUE ONE : **145** and SUCCESSOR VALUE : **146**

##### Multiply both the value : **21170**

### STEP 3 :
