**long division method**’ that was taught to us in school. Here, we are going to discuss the shortcut to finding square root of a number.

**Importance Of How To Find Square Root Of A Number In Less Time?**

**If you have a question from simplifications, where you need to find square root in one of the steps, consider the given number to be a perfect square.**ONLY when the question is given under the topic approximations, it may not be a perfect square.

**How To Find Square Root Of A Number In Three Easy Steps**

Firstly, you must memorise the squares of numbers from 1 to 30.

We have already learnt that there is a certain pattern seen when it comes to square of any number:

**Decide the unit’s place of the result.**

**Leave the last 2 digits and find the immediate perfect square before the remaining number.**

**That is the number in ten’s place**

**To determine whether the square root of 2401 is 41 or 49**

**Take the number that lies exactly between 41 and 49 and square it.**

**Square root of 2401 is 49**

**Decide the unit’s place of the result.**

**Leave the last 2 digits and find the immediate perfect square before the remaining number.**

**To determine whether the square root of 6084 is 72 or 78**

**Take squares of numbers 70 and 80, since 72 and 78 lie within the range.**

**Square root of 6084 is 78**

**Decide the unit’s place of the result.**

Step 2: **Leave the last 2 digits and find the immediate perfect square before the remaining number.**

__11__3 or

__11__7

**To determine whether the square root of 12769 is 113 or 117**

**Square root of 12769 is 113**

**Square root of 12769 is 113**
