## What Is the Square Root of 35?

The square root of 35 is a number whose square gives the original number. By trial and error method, we can see that, there does not exist any integer whose square is 35.

The value of **√**35 is 5.91607978309961...

To check this answer, find (5.91607978309961)^{2} and we can see that we get 34.999... which is very close to 35.

## Is the Square Root of 35 Rational or Irrational?

A rational number is a number which can either be:

- either terminating
- or non-terminating and has a repeating pattern in its decimal part.

In the previous section, we saw that: **√**35 = 5.91607978309961...

Clearly, this is non-terminating and the decimal part has no repeating pattern. So it is NOT a rational number. Thus, **√**35 is an irrational number.

## How to Find the Square Root of 35?

It is possible to find the square root of 35 using various methods.

- Repeated Subtraction
- Prime Factorization
- Estimation and Approximation
- Long Division

### Simplified Radical Form of Square Root of 35

To find the square root of any number, we take one number from each pair of the same numbers from its prime factorization and we multiply them. But the prime factorization of 35 is 5 × 7 which has no pairs of the same numbers. Thus, **√**35 cannot be simplified any further and hence the simplest radical form of **√**35 is **√**35 itself.

### Square Root of 35 by Long Division Method

The square root of 35 can be found using the long division as follows.

**Step 1**: In this step, we take 35 as a pair (by placing a bar over it). (If the number has an odd number of digits, then we place a bar just on the first digit; if the number has an even number of digits, then we place a bar on the first two digits together).**Step 2**:^{2}=35. So 5 is such a number. We write it in the place of both the quotient and the divisor.**Step 3**: Since we do not have any other digits of 35 to carry forward, we write pairs of zeros after the decimal point (as 35 = 35.000000...). We write as many pairs as we want the number of decimals after the decimal point in the final result. Let us calculate**√**35 up to 3 decimals. So, we write 3 pairs of zeros. Since we have taken a decimal point in the dividend, let us write a decimal point in the quotient as well after 5.**Step 4**:**Step 5**:**Step 6**: We repeat step 3 and step 4 for the corresponding divisors and quotients of the subsequent divisions.

So far we have got **√**35 = 5.916

If we repeat this process further, we get, **√**35 = 5.91607978309961...

**Important Notes:**

- 35 lies between 25 and 36. Among these, 35 is very close to and less than 36. So
**√**35 is very close to and less than**√**36 = 6. - The prime factorization method is used to find the square root of a perfect square number. For example: 36 = 2 × 2 × 3 × 3 = 2
^{2}× 3^{2 }. So,**√**36 =**√**2^{2}× 3^{2}= 2 × 3 = 6.

**Think Tank:**

- Can the value of
**√**35 be -5.91607978309961... as well? Hint: Think what is the value of (-5.91607978309961...)^{2} - Is
**√**35 a real number? Hint: Think whether there is any real number whose square is negative.

## Square Root of 35 Solved Examples

**Example 1**: The ratio of the side lengths of the two squares is 9:10. The area of the second square is 3500 square inches.Then, what is the side length of the first square?**Solution**Since the sidelengths of two squares are in the ratio 9:10, we can assume them to be 9x inches and 10x inches.Then the area of the second square is 10x × 10x = 100x

^{2}square inches.

Using the given information,

100x^{2}&= 3500

x^{2}= 35

x =**√**35 inches

So the side length of the first square is, 9x= 9**√**35 = 53.24471 inches-
**Example 2**: The area of a square-shaped window is 35 square inches. Can you find the length of the window?**Solution**Let us assume that the length of the window is x inches. Then its area using the formula of area of a square is x

^{2}square inches. By the given information, x^{2}= 35. By taking the square root on both sides,**√**x^{2 }=**√**35. We know that the square root of x^{2}is x. The square root of 35 is 5.9160.

Therefore, the length of the window is 5.9 inches.
