What Is the Square Root of 140?
The square root of 140 is an irrational number, meaning that it cannot be expressed as a simple fraction or decimal. Instead, it goes on infinitely without repeating, making it challenging to calculate precisely. However, we can estimate the value of the square root of 140 by using several different methods.
Estimating the Square Root of 140 Using Prime Factorization
One way to estimate the square root of 140 is to use prime factorization. Prime factorization involves breaking down a number into its smallest prime factors. For example, the prime factorization of 140 is 2 x 2 x 5 x 7. To find the square root of 140, we can pair up the prime factors in groups of two and take their square roots. This gives us the equation:√(140) ≈ √(2x2) x √(5x7)Simplifying this equation gives us:√(140) ≈ 2√(35)Therefore, the approximate value of the square root of 140 is 2√35.
Estimating the Square Root of 140 Using a Calculator
Another way to estimate the square root of 140 is to use a calculator. Most calculators have a function for finding square roots, which can quickly give us an approximate value. In this case, the square root of 140 is approximately 11.83. However, keep in mind that this value is not exact and may have some rounding errors.
Using Long Division to Find the Square Root of 140
If we want to calculate the square root of 140 precisely, we can use long division. This method involves dividing the number into groups of two digits and then finding the largest digit that can be squared without exceeding the current remainder. We repeat this process until we have enough decimal places or reach the desired level of precision.
The Steps to Find the Square Root of 140 Using Long Division
1. We start by separating the number 140 into groups of two digits: 14 and 00.2. We find the largest number whose square is less than or equal to 14, which is 3. We write this number above the 14 and subtract 9 from 14, leaving us with a remainder of 5.3. We bring down the next group of digits (00) and add it to the remainder, giving us 500.4. We double the number above the line (3) to get 6 and then find the largest number whose product with itself is less than or equal to 50, which is 7. We write this number next to 3, giving us 37.5. We subtract 49 from 50, leaving us with a remainder of 1.6. We bring down the next group of digits (00) and add it to the remainder, giving us 100.7. We double the number above the line (37) to get 74 and then find the largest number whose product with itself is less than or equal to 100, which is 10. We write this number next to 37, giving us 3710.8. We subtract 100 from 100, leaving us with a remainder of 0.9. Therefore, the exact value of the square root of 140 is 11.8321595662 (rounded to ten decimal places).
