think what number you can multiply by theirselves that the answer is the number

you use T.A.E or Trial And Error

By using factors but use same number if possible but if can’t then you can use other numbers.
Ex.:
√4 = 2×2 or 2² = put one of the 2 outside because it has a square(²) and = 2√1 or 2
√20 = 2x2x5 or 2²x5 = put one of the 2 outside = five will be left inside because it doesn’t have ² = 2√5 or 4.47

Answer:

How to find square roots without calculators

Let’s move on to see some square root examples, and learn how to find answers for square roots. You’ll first have to keep in mind the steps to finding square roots and they are:

Estimate: Get as close as possible to the number you’re trying to square root by finding two perfect square roots that gives a close number.

Divide: Divide your number by one of the square roots you’ve chosen from the previous step.

Average: Take the average of step 2 and the root.

Repeat: Keep repeating steps 2 and 3 using the results you got from step 3 until you get a number that’s accurate enough for you to answer the question.

So in simpler words, to estimate square roots which are not perfect squares without using a calculator, we’ll need to know the perfect square numbers well. We will first put the number inside the square root sign in the middle of a number line, and then find the two closest perfect square numbers on its left and right hand side to make the best estimation. Take a look at some of the below examples of square roots.

Square root of 5

Step 1: Estimate

The square numbers of 2 and 3 are 4 and 9 respectively. The number 5 lies between these two numbers.

Step 2: Divide

Divide 5 by either 2 or 3. In this case, let’s choose 2. We’ll get 2.5.

Step 3: Average

Average 2.5 and 2, which gives us 2.25.

Step 4: Repeat

To get a more accurate number, keep repeating step 2 and 3. In that case we’d take 5 and divide it by 2.25, which equals 2.222. Average out 2.22 and 2.25, giving us 2.235. You may repeat steps 2 and 3 as many times needed to get a more accurate number.

The final answer for the square root of 5 is approximately 2.23!

Square root of 8

Step 1: Estimate

8 lies between perfect squares of 2^2 and 3^2.

Step 2: Divide

Divide 8 by 3. We get 2.6666666

Step 3: Average

Average 2.6666666 and 3, which gives us 2.8333333

Step 4: Repeat

To get a more accurate number, keep repeating step 2 and 3.

You should get a final answer of 2.83.

Square root of 10

Step 1: Estimate

10 lies between perfect squares of 3^2 and 4^2.

Step 2: Divide

Divide 10 by 3. We get 3.33

Step 3: Average

Average 3.33 and 3, which gives us 3.1667

Step 4: Repeat

To get a more accurate number, keep repeating step 2 and 3.

You should get a final answer of 3.16.

Square root of 6

Step 1: Estimate

6 lies between perfect squares of 2^2 and 3^2.

Step 2: Divide

Divide 6 by 2. We get 3.

Step 3: Average

Average 3 and 2, which gives us 2.5

Step 4: Repeat

To get a more accurate number, keep repeating step 2 and 3.

You should get a final answer of 2.45.

Square root of 12

Step 1: Estimate

12 lies between perfect squares of 3^2 and 4^2.

Step 2: Divide

Divide 12 by 4. We get 3.

Step 3: Average

Average 3 and 4, which gives us 3.5.

Step 4: Repeat

To get a more accurate number, keep repeating step 2 and 3.

You should get a final answer of 3.46.

Square root of 20

Step 1: Estimate

20 lies between perfect squares of 4^2 and 5^2.

Step 2: Divide

Divide 20 by 5. We get 4.

Step 3: Average

Average 4 and 5, which gives us 4.5.

Step 4: Repeat

To get a more accurate number, keep repeating step 2 and 3.

You should get a final answer of 4.47.

Square root of 0

As a final note, we wanted to explore what the square root of 0 is. You can’t take the square root of a negative number, but 0 is not a negative number. The square root of 0 is actually 0!

Step-by-step explanation:

1. find the perfect square that is close to non-perfect square

(e.g [tex]sqrt{12}[/tex] the perfect square that is near to it was [tex]3^{2}[/tex] which results to 9, if you try [tex]4^{2}[/tex] you will exceed to 12 therefore it is between 3 and 4)

2. estimate (pick number between 3 and 4)

e.g [tex]3.5^{2}[/tex]=12.25 which is close to 12, so we can consider 3.5 as its approximate estimate for the [tex]sqrt{12}[/tex]

## How to solve square roots of any number without calculator?

Ask: How to solve square roots of any number without calculator?

Answer:

Try the following methods below.

Step-by-step explanation:

Enlisting method:

1 x 1 = 1

2 x 2 = 4

3 x 3 = 9

4 x 4 = 16

5 x 5 = 25

6 x 6 = 36

7 x 7 = 49

8 x 8 = 64

9 x 9 = 81

10 x 10 = 100

11 x 11 = 121

12 x 12 = 144

13 x 13 = 169

14 x 14 = 196

15 x 15 = 225

For another method, you can use the number line method which you will enlist too like the other one above.

Another, you can use a simple method which by just dividing the number by using a paper, like how you add numbers since you were in lower grades (elementary).

In addition, you can also use the method that uses estimation, like:

Square root of 4761

Estimation: 50±

Trial: 50 x 50 = 2500

Another estimation: 60±

Trial: 60 x 60 = 3600

Estimation, again: 65±

Trial: 65 x 65 = 4225

Seems near to the square root. So, now you will try to estimate it by increasing it in +1 pattern:

Estimation +1 pattern:

Trials: 66 x 66 = 4356

67 x 67 = 4489

68 x 68 = 4624

69 x 69 = 4761

Now, you found the square root of the given number by using estimation.

Those methods are the ones that can solve square roots without the calculator.

Good luck!
