Square Root of 1159
If a number is multiplied by itself, the result is a square. The inverse of the square is a square root. The square root is used in various fields such as vehicle design, finance, etc. Here, we will discuss the square root of 1159.
What is the Square Root of 1159?
The square root is the inverse of the square of the number. 1159 is not a perfect square. The square root of 1159 is expressed in both radical and exponential form. In the radical form, it is expressed as √1159, whereas (1159)^(1/2) in exponential form. √1159 ≈ 34.0454, which is an irrational number because it cannot be expressed in the form of p/q, where p and q are integers and q ≠ 0.
Finding the Square Root of 1159
The prime factorization method is used for perfect square numbers. However, for non-perfect square numbers, the prime factorization method is not applicable. Instead, long-division and approximation methods are used. Let us now learn the following methods:
- Prime factorization method
- Long division method
- Approximation method
Square Root of 1159 by Prime Factorization Method
The product of prime factors is the prime factorization of a number. Now let us look at how 1159 is broken down into its prime factors.
Step 1: Finding the prime factors of 1159 Breaking it down, we get 7 × 13 × 127. Since 1159 is not a perfect square, these factors cannot be paired. Therefore, calculating 1159 using prime factorization as a perfect square is impossible.
Square Root of 1159 by Long Division Method
The long division method is particularly used for non-perfect square numbers. In this method, we should check the closest perfect square number for the given number. Let us now learn how to find the square root using the long division method, step by step.
Step 1: Group the numbers from right to left. For 1159, group it as 59 and 11.
Step 2: Find n whose square is ≤ 11. We can say n as ‘3’ because 3 × 3 = 9, which is less than 11. Now the quotient is 3, and the remainder is 11 - 9 = 2.
Step 3: Bring down 59 to make the new dividend 259.
Step 4: Double the quotient and use it as the new divisor's first digit: 3 × 2 = 6.
Step 5: Now find a digit x such that 6x × x is less than or equal to 259. Try 4: 64 × 4 = 256.
Step 6: Subtract 256 from 259 to get the remainder 3.
Step 7: Since the remainder is less than the divisor, add a decimal point and two zeroes to continue. The new dividend is 300.
Step 8: Repeat the process to find more decimal places. So the square root of √1159 ≈ 34.0454.
Square Root of 1159 by Approximation Method
The approximation method is another approach for finding square roots. It is an easy method to estimate the square root of a given number. Now let us learn how to find the square root of 1159 using the approximation method.
Step 1: Find the closest perfect squares of √1159. The smallest perfect square less than 1159 is 1156 (34²) and the largest perfect square more than 1159 is 1225 (35²). √1159 falls between 34 and 35.
Step 2: Use interpolation to approximate: (1159 - 1156) / (1225 - 1156) = 3 / 69 ≈ 0.0435. Adding this to the lower bound: 34 + 0.0435 ≈ 34.0454. Therefore, the square root of 1159 is approximately 34.0454.
Common Mistakes and How to Avoid Them in the Square Root of 1159
Students often make errors while finding the square root, such as forgetting about the negative square root or skipping steps in the long division method. Here are a few common mistakes:
Mistake 1
Forgetting about the negative square root
It is crucial to understand that a number has both positive and negative square roots. However, we typically refer to the positive square root as it is more commonly used.
For example, √1159 ≈ 34.0454, but there is also -34.0454.
Mistake 2
Not adding the square root symbol in proper places
Misplacing the square root symbol is a common mistake. It is essential to simplify the expression within the square root first.
For example, √(9 + 16) ≠ √9 + √16. The correct simplification is √(25) = 5.
Mistake 3
Not finding the correct value of a non-perfect square
When dealing with non-perfect squares, it's important to approximate correctly.
For example, √1159 ≈ 34.0454, not 34 or 35.
Mistake 4
Confusing the square root symbol with the cube root
It is vital to distinguish between square roots and cube roots.
For example, √64 = 8 but ∛64 = 4.
Mistake 5
Making mistakes in long division
The long division method involves multiple steps, which can lead to errors if steps are skipped or miscalculated, such as in subtraction or choosing the next digit of the quotient.
Square Root of 1159 Examples
Problem 1
Can you help Max find the area of a square box if its side length is given as √1159?
The area of the square is approximately 1343.0881 square units.
Explanation
The area of the square = side².
The side length is given as √1159.
Area of the square = (√1159)² = 1159.
Problem 2
A square-shaped building measuring 1159 square feet is built. If each of the sides is √1159, what will be the square feet of half of the building?
579.5 square feet
Explanation
We can divide the given area by 2 since the building is square-shaped. Dividing 1159 by 2 = 579.5. So half of the building measures 579.5 square feet.
