Question

Is there any formula of square root?

Answer 1

Step-by-step explanation:

no there is method like long division and making factor

Answer 2

Answer:

There are 3 formula to find that the no. is a perfect sq. or not

The steps are:

1. Prime Factorisation Method
2. Long Division Method
3. Repeated subtraction Method

Step-by-step explanation:

Prime Factorisation Method:

Like the no. is 36 To find the √36 the method is

2 | 36

2 | 18

3 | 9

3 | 3

| 1

So, 36 = 2×2×3×3

= 2²× 3²

= (2×3)²

=. 6²

Hence, the √36 = 6

Long Division Method:

Like the no. is 121 To find the √121 the method is

1 | 121 ( 11

+1 - 1

2 1 | 021

21

0

Hence, the √121 = 11

Repeated Subtraction Method:

Like the no. is 25

Subtract the odd no. with the given no.

25-1 = 24, 24-3=21, 21-5=16, 16-7=9, 9-9=0

Then, Count the odd no.s how many you subtracted..

So By counting the odd no. they are 5

So, the √25 = 5

May this helps you...
