What is the division method for finding square root of a number?

Answer 1

its quite simple actualy.
first put a decimal at the no n after dat put zeros ,n comin reverse make pairs of two numbers. next see whts the no tht has a square nearest to the no. lik suppose 26 is the no den take 5 X 5 =25.
now add 5+5 +10. now it gets a bit tricky. u hv to search for a digit after 10_ tht when its is multiplied by 10_ u get the closest multiple. lik u hv 10 then u hv to take 102 X 2 . i.e multiply with the digit u hv taken at the end. eg- 105 X 5. go on multiplying lik tht.


i know ntn of this has gone in ur head. did the best to explain it to u. use a calci or ask ur maths teacher.

Answer 2

There's a method called long-division method. Here's how it goes:
>>Take the number you want to find the root for. Starting backward group two numbers together. If you have one numer left, dont do anything to that one number.
>>Choose a number whose square nearly equals that number(or those two numbers)
>>If you get a remainder, instead of bringing down one number, as in normal division, you bring down the grouped numbers, one at a time.
>>Now take the quotient and multiply it by 2. Use that number as the 10's (or 100's) digit and choose a number for the unit's one. When you multiply the bigger number with the one you have used as the unit's digit, you should get a number which nearly equals (or equals) the remainder (like normal division).
>>If you want to use decimals, always use the zero's in pairs.

Eg. Finding the root of 2500

2500/5
=00
So, you put a zero after 5.
Therefore, root of 2500 is 50

Somebody else asked this only 3 days ago. Here is the web site I found for him, which explains the method.

Answer 4

Ask Dr. Math, he is da man when it comes to this stuff. He will give you some simple and or very lengthy explanations to help you fully understand the whole concept.
