Methods to Find Value of Root 61
There are several methods to approximate the value of the square root of 61. Here are a few common ones:
1.Long Division Method: This is a manual method where you perform long division to approximate the square root. It involves repeatedly subtracting perfect square numbers from the given number and bringing down pairs of digits until you achieve the desired level of accuracy.
2.Newton’s Method: Also known as the Newton-Raphson method, it’s an iterative numerical method for finding the roots of a real-valued function. It involves repeatedly applying a simple formula to refine the approximation until the desired level of accuracy is achieved.
3.Using a Calculator or Software: Most calculators and mathematical software have built-in functions to compute square roots accurately. You can simply input √61 into a calculator or use a mathematical software package to find the approximate value.
4.Binomial Expansion: This method involves using the binomial expansion theorem to expand the square root expression into a series. By truncating the series at a certain point, you can obtain an approximation for the square root.
5.Approximation with Known Square Roots: You can approximate √61 by finding the nearest perfect squares (such as √49 and √64) and then linearly interpolating between them to get a rough estimate.
Square Root of 61 by Long Division Method
Step 1: Start with the Number: Think of the number 61. We want to find which number, when multiplied by itself, gives a result close to 61 without going over.
Step 2: Initial Guess: Start by finding a simple square number less than or equal to 61. The closest one is 49, which is 7 squared (7×7=49). So, our first guess is 7.
Step 3: Subtract and Bring Down: Subtract 49 from 61, which gives us 12. This is our remainder. In the long division method, we would normally “bring down” the next digits, but since there are none, we can start adding decimal places to 61, treating it as 6100, 610000, and so on, for more precision.
Step 4:Refine Your Guess: Double your current guess (7×2=14) and write it down with a space for a new digit (14_). This is your new divisor. Now, you need to find a digit to put in the blank that, when added to 14_, gives a product less than or equal to your current dividend (in the first step, this is 1200, because we’re treating the remainder 12 as 1200 for more precision). This digit is also your new quotient digit.
Step 5:Repeat for Precision: Subtract the product of your new divisor and the new digit from the dividend, get the new remainder, and repeat the process for as many decimal places as you want. Each time, you’re doubling the entire current quotient (ignoring the decimal) for the new divisor, guessing a digit to complete it, and checking if the product is less than the current dividend.
Step 6: Continue Until Satisfied Keep repeating the process, adding pairs of zeros and calculating subsequent digits of the square root. You can continue this for as many decimal places as you require.
61 is Perfect Square root or Not?
A perfect square is a number that can be expressed as the product of an integer with itself. For example, 4, 9, 16, and 25 are perfect squares because they can be expressed as 2×2, 3×3, 4×4, and 5×5 respectively.
However, the square root of 61 is an irrational number because it cannot be expressed as the ratio of two integers, and its decimal representation goes on infinitely without repeating any pattern. The approximate value of √61 is approximately 7.81024967591.
FAQ’s
How do you simplify √ 61?
The number 61 is a prime number. This implies that the number 61 is pairless and is not in the power of 2. Therefore, the radical form of square root of 61 cannot be simplified further.
Which number is closest to √ 61?
The square root of 8 is 64, the square root of 7 is 49. 61 is closer to 64. Integers cannot be fractions, so the answer of 7.8 is rounded up to 8!
