Square Root of 1156
Squaring and finding the square root are inverse operations. When 1156 = a number × a number, then √1156 = a number. In this lesson, we will calculate the square root of 1156 by repeated subtraction method and prime factorization method and solve a few interesting problems.
- Square Root of 1156: √1156 = 34
- Square of 1156: 1156² = 13,36,336
What Is the Square Root of 1156?
- The square root of a number is the number that when multiplied to itself gives the original number as the product. Finding the square root of a number is the inverse process of squaring a number.
- 1156 = a × a = a2
- Thus, a = √1156= √(34 × 34)
- 34 ×34 = 1156 or -34 × -34 = 1156. Therefore √1156= ± 34
- This shows that 1156 is a perfect square.
Is the Square Root of 1156 Rational or Irrational?
- A rational number is defined as a number that can be expressed in the form of a quotient or division of two integers, i.e. p/q, where q is not equal to 0.
- 1156 can be expressed as 34/1 and -34/1
- Both the numbers can be represented in the form of a rational number.
- Hence, the square root of 1156 is a rational number.
How to Find the Square Root of 1156?
The square root of 1156 can be calculated using different methods such as prime factorization or the repeated subtraction method.
Square Root of 1156 by Repeated Subtraction Method
- The sum of n consecutive odd numbers = n2 . 1156 is the sum of first 34 odd natural numbers. 342 = 1156
- 1 + 3+ 5+ 7+ 9 + 11+ 13 + 15 + 17 + 19 + 21 + 23+ 25 + 27 + 29 + 31+ 33+ 35 + 37 + 39 + 41 + 43 + 45 + 47 + 49 + 51 + 53 + 55 + 57 + 59 + 61 + 63 + 65 + 67 = 342 = 1156
- Start from 1156 and keep subtracting the successive odd numbers till we obtain zero. The number of times we subtract is the square root of 1156.
- Therefore starting from 1156, we subtract 34 times to obtain 0. Thus, the square root of 1156 is 34.
Square Root of 1156 by Prime factorization method
- Prime factorization is expressing the number as a product of its prime factors.
- The prime factor of 1156 is 3. 1156 = 2 × 2 × 17 × 17
- The square root of 1156 is √1156 = √( 2 × 2 × 17 × 17)
- √1156 = √( 22 × 172) ⇒ (1156½ ) = ( 2 ½ × 17½ )
- Squaring on both the sides, (1156½ )2 = ( 2 ½ × 17½ )2
- We get 1156½ = 2 × 17 = 34

Square Root of Solved Examples
-
Example 1: How can we divide 1156 using the division method?
Solution:
Write 1156 as 11 56 in pairs. 11 is the dividend now.
Find a (number x number) that gives ≤ 11. We find 3 × 3 = 9. subtract 9 from 11 and obtain 2 as the remainder.
Bring down the next pair of 56. 2 56 is our new dividend.
Double the quotient. It is 6. Now 60 is written in the new divisor's place.
Find a (number + 60) × number that gives the result ≤ 2 56. We determine that (60 + 4) × 4 = 256.
Subtract this from 256. We have completely divided 1156 as we have obtained the remainder as 0.
Thus, √1156 = 34

Example 2 : James has to buy a new carpet for the prayer hall. In the store, he finds a square carpet of area 1156 sq feet. How long is each side of the carpet? How many such carpets does he need to cover the hall of area 272 sq feet?
Solution:
Area of the square carpet = 1156 sq feet
The side of the carpet = √Area = √1156
Side = 34 feet
Number of carpets needed = 272 ÷ 34 = 8
