Square Root of 130
Square root is the number obtained when a number is multiplied with itself. We apply the concept of square root in architecture, to measure volume and surface area. In this article, we’ll learn how to find the square root of 130.
What is the Square Root of 130
The square root of 130 is ±11.4018. Finding the square root of a number is the inverse process of finding the perfect square. The square root of 130 is written as √130.
Finding the square root of 130
The different ways to find the square root of a number are prime factorization, long division and approximation/estimation method.
Square root of 130 using prime Factorization Method
The prime factorization of 130 breaks 130 into its prime numbers.
The numbers 2, 5 and 13 are the prime numbers
Prime factorization of 130 is 2 × 5 × 13
Since 2, 5 and 13 are not repeating, we can’t pair them
Therefore, √119 is expressed as √2 x √5 x √13, the simplest radical form
Square root of 130 using long division method
The long division method finds the square root of non-perfect squares.
Step 1: Write down the number 130
Step 2: Number 130 is a three-digit number, so pair them as (1), (30)
Step 3: Find the largest that is closest to the first pair (1), which is 12
Step 4: Write down 1 as the quotient, which will be the first digit of the square root.
Step 5: Subtracting 12 from 1 will leave zero as the remainder. Now bring down the second pair (30) and place it beside 0.
Step 6: Now double the quotient you have, that is added the quotient 1 with 2 and the result will be 2
Step 7: Choose a number such that it can be placed after 2. The two-digit number created should be less than the second pair (30). Here, we number 1 after 2, because the number formed will be less than 30.
Step 8: Subtract 21 from 30 → 30-21 =9. Now add a decimal point after the new quotient and adding two zeros will make it 900
Step 9: Apply step 7 over here and continue the process until you reach 0.
Step 10: We can write √30 as 11.4017
Square root of 130 by Approximation method
The approximation method finds the estimated square root of non-perfect squares.
Step 1: Identify the closest perfect square to 130. Numbers 121 and 144 are the closest perfect square to 130.
Step 2: We know that √121 = 11 and √144 = 12. Thus, we can say that √130 lies between 11 and 12.
Step 3: Check if √130 is closer to 11 or 12. Let us take 11.5 and 12. Since (11.5)2 is 132.25 and (12)2 is 144, √130 lies between them.
Step 4: We can keep changing the values of 11.5 to 11. 6 and iterate the same process without changing 12 as the closest perfect square root.
The result of √130 will be 11.4017
Common Mistakes and How to Avoid Them in Square Root of 130
Take a look at mistakes a child can make while finding the square root of 130:
Mistake 1
Trying to guess the square root instead using the methods
Finding square roots for non-perfect squares without using the method is time-consuming. Always use the long division method to find the square root of non-perfect squares. Using the long-division method, we can find √130 as 11.4017.
Mistake 2
Misunderstanding the square root of 130 with the division
A kid might divide 130 by 2, assuming that the result will give the square root. Understand the difference between finding a square root and dividing a number. A square root is the number that gets multiplied two times.
Mistake 3
Calculation mistake in subtracting the digits
Always be sure that you have checked the arithmetic calculations. If you subtract the digits incorrectly, the square root you get will also be incorrect.
Square Root of 130 Examples
Problem 1
Find the value of (√130/3)
The value of (√130/3) is 3.8005
Explanation
Find the approximate value of √130, which is 11.4017. Divide the approximate value by 3 to get 3.8005 (11.4017 ÷ 3 = 3.8005)
Problem 2
Calculate the difference between square root of 130 and square root of 81
The difference is 2.4017
Explanation
The approximate value of the square root of 130 is ±11.4017 and the square root of 81 is ±9. Now subtract 9 from 11.4017 to get 2.4017
Problem 3
If b = √130, what is b² - 130?
The value for b2 - 130 is 0
Explanation
We know that b = √130, now b2 =130. Therefore, b2 - 130 = 130-130 = 0.
Problem 4
Write √520 in terms of √130
√520 can be written in terms of √130 as 2√130
Explanation
√520 with the help of prime factorization is written as 23 × 5 × 13. To express it in terms of, √520 is written as 2√130
