How many ways to find square rost of numbers ? Excplain
each methods.
Answers
Answer:
1)prime factorization method
2)long division method
totally there are 2 methods to find square root of a number
1)its like lcm.you want to make a pair of same numbers and mention it as one and then multiply that numbers.
the third image is about the long division method.
i hope it helps you! thank you!!!!

Step-by-step explanation:
long division method:- first , you have to start taking two numbers from right side and make them a pair ( no problem if there is no pair at the left end, single number can come in the left end ) , then you have to start doing division from left side as usually we do in simple division but only square roots can be taken in the divisor ( like 2*2,3*3,4*4,5*5.etc.....)after we solve the first pair/single number in the leftmost side we can start with the next pair, we need a new divisor for that pair so we multiply 2 with the quotient.After we get product we have to add another square root number, one to its side and the same we have to add in the quotient so that we get our paired dividend or the number nearest to the dividend (product of the roots should not be greater than the dividend) as the product of the square roots when we multiply our new square root number in the quotient and our new divisor for the new pair....After solving all the pairs in the same way we get a final quoitent and that is square root of the whole dividend question.
Prime factorisation:-It is same as HCF LCM. We have to do HCF and then pair same numbers as we do in LCM and take only one number from each pair and then the multiply the chosen numbers. The product we get is the square root of the number.......If there is one number left without pair then we can add them a root {√} so in this case we get a number with a root ( eg:- 12√3,4√5......)
Hope it will be helpful....
