Find square root by vedic maths

1.   We have to look at the numbers from 1 to 9.

     Square of 1 (12)=   1
Square of 2 (22)=   4
Square of 3 (32)=   9
Square of 4 (42)= 16
Square of 5 (52)= 25
Square of 6 (62)= 36
Square of 7 (72)= 49
Square of 8 (82)= 64
Square of 9 (92)= 81

2.     From this we can infer that
Square root of any number which ends with 1 will end with 1 or 9 (1+9=10).
Square root of any number which ends with 4 will end with 2 or 8 (2+8=10).
Square root of any number which ends with 9 will end with 3 or 7 (3+7=10).
Square root of any number which ends with 6 will end with 6 or 4 (6+4=10).

If the square ends in

        1

       4

       9

       6

        5

        0

The no. would end in

      1,9

     2,8

     3,7

     4,6

        5

        0


These facts are very logical and easy to remember. You have to understand the logic behind it easily.

In vedic mathematics to find the square root of  numbers which are perfect squares, the specific method is applied.


Illustration 1:- 2304

Solution:-

Step 1:- At first we take two parts of given number

1st part                2nd part

   23                          04     

Note:-2nd part have last two digit always & rest in 1st part.

Step 2:- 42 < 23 < 52

we take 4 is the 1st part of answer.(Always take least number)

Step 3:- Last digit is 4 , it means 2 or 8 is the 2nd part of answer.

23 is near the square of 5 and not with the square of 4

So 2nd part of answer is 8 (greater part)

Note:- If 23 is near the square of 4 then 2nd part of answer is 2 (lesser part)

Step 4:- Answer is 48


Illustration 2:- In 23716

Solution:-

Step 1:- At first we take two parts of given number

1st part                2nd part

   237                      16     

Note:-2nd part have last two digit always & rest in 1st part.

Step 2:- 152 < 237 < 162

we take 15 is the 1st part of answer.(Always take least number)

Step 3:- Last digit is 6 , it means 4 or 6 is the 2nd part of answer.

237 is near the square of 15 and not with the square of 16

So 2nd part of answer is 4 (lesser part)

Note:- If 237 is near the square of 16 then 2nd part of answer is 6 (greater part)

Step 4:- Answer is 154

Remember the following:

1.     You should know the squares of all numbers from 1 to 9.

2.    You should remember, depending on the last digit of the given number , how to arrive at the last digit of the answer.

3.     Use logical decisions, rather than formula to arrive at the right answer.

Square of the number

     This article is used to find out the square of  a number in a short period of time compare to normal maths. It increase the speed of your calculations.  The answer obtained by multiplying a number by itself is the square of that number. Example :- 6×6= 36 which is the square of 6.                          8×8= 64 which is the square of 8.      1.   Square of numbers ending in 5 :- Example 1-: 35 2 =   ? Step 1:- Multiply the first part by the first part plus 1: 3 ×(3+1) =3×4 =12 Step 2:- Write the number 25 next to the result from step 1: 35 2 = 12_25 = 1225 Example 2-: (in 3 digits) 125 2 =   ? Step 1:- Multiply the first part by the first part plus 1: 12 ×(12+1) =12×13 =156 Step 2:- Write the number 25 next to the result from step 1: 125 2 = 156_25 = 15625 Example 3-: (in decimal numbers) 9.5 2 =     ? Step 1:- M...

WORLD  HERITAGE  SITES IN  INDIA PART- 1  Why did UNESCO start the World Heritage Centre? The UNESCO World Heritage Centre was born by merging two separate movements. The first was a movement for the preservation of cultural sites. The second was a movement that dealt with the conservation of nature. The ball for the first movement was set rolling with the decision to build the Aswan High Dam in Egypt. This dam would have flooded the valley in which one of the treasures of ancient Egypt- the Abu Simbel temple- wsa located. In 1959 UNESCO launched a campaign to safeguard these temples. It was a joint effort of 50 countries, and it led to many other similar projects to safeguard rare treasures. It was the United States that led the movement to combine the conservation of natural wonders along with cultural sites.  World Heritage Fund- If 1972, the World Heritage Fund was created. Its aim is to assist nations in identifying, preserving, and promoting World Heritage...

What is Genetics

What is Genetics?     Have you ever wondered why some people are short while others are tall, or why some have brown eyes while others have black eyes? Genetics is the study of the ways in which different characteristics are passed from each generations of living things to the next. Genetics has many divisions like population genetics and epigenetics   What is DNA?     Each of us has a unique set of chemical blueprints that determine how our body looks and functions. These blueprints are contained in our DNA, which is the short form of deoxyribonucleic acid.    DNA is in the form of long spiral-shaped molecules found inside every cell. The instructions for constructing and maintaining cells are built into this molecule. DNA can copy itself so that all the new cells produced by a plant or animal, contain copies of the same set of genetic instructions, or genetic code. Every single living organism processes DNA. In fact, DNA defin...
