An exponent of a number indicates how many times a number is multiplied by itself. A negative exponent indicates how many times the reciprocal of the base must be multiplied. A fractional exponent is a number’s exponent that is a fraction. Square roots and cube roots. The inverse of squaring is a square root. When we determine the inverse of a number, we frequently express it as a square. It is probably wondering how to describe the inverse square operation. This is where the utilization of the root notion comes into play.
When we multiply a number by itself, we get the result twice the under root. This is known as the under the root of a number.
Let us discuss the value of root 2,

Mathematical Value of √2
√2: This is how to denote the square root of two.
We may even put it in exponential form as (2)1/2. We obtain 1.4142135624 if we round √2 up to 10 decimal places.
The answer to the equation x2=2 is also 1.4142135624.
There are three methods to describe the value of square root 2. The three forms are listed below.
- 1.4142135624 in decimal format
- Under root of 2 is written as √2 in radical format.
- (2)1/2 can be written in exponential form.
Now let us discuss the when was √2 was first evaluated
When did the value of root 2 become known?
The Greeks were the first to discover the beneath root notion. While splitting integers, they discovered that a handful of them could not be divided in p/q form, where q is not equal to 0. The notion was eventually dubbed the under-root concept, and it was determined to be a rational number.
The same under root notion is utilized in Pythagoras’ Theorem to identify the third side of a triangle when we know two of the other sides.
Now let us discuss √2 is rational or irrational,
We know the value of √2 up to 1 trillion decimal points. As a result, it is currently regarded as an irrational number.
How do you calculate the value of the root of 2?
Now that we’ve learned enough about under root 2, let’s look at how to locate an under root of 2. There are two methods for determining a number under root. They’re
- Method of Long Division
- Method of Estimation
Long Division Method
Long division is a way of dividing big numbers into groups or pieces in mathematics, Long division aids in breaking down the division difficulty into a series of simpler phases. As with other division problems, a large number, known as the dividend, is divided by another integer, known as the divisor, to get a result known as the quotient and, in certain cases, a remainder, Long division may also be used to split decimal numbers into groups that are equal in size.
The long division technique can be used to calculate the Value of Root 2
To determine the root of 2 using the long division method, follow the steps below.
- the greatest number whose square is less than or equal to 2.
- Make use of the number as a quotient and divisor. To get the remaining, divide it by two.
- Put a decimal after 1 in the quotient. Add two zeros to the right of the remainder.
- Divide the divisor by two and leave a blank space on the right.
- Determine the greatest digit such that when the new divisor is multiplied by the quotient, the product is less than or equal to the dividend.
- Repeat the process until the appropriate number of decimal points is reached.
- If you complete the instructions correctly, the final result should be 1.4142.
Estimation Method
To determine the under root of 2 using the estimate approach, follow the steps below.
- Y n+1= ((x/Yn) + Yn)/2 is the formula to be applied.
- Repeat the procedure until the appropriate number of decimal points is reached.
- y1 = (2 + 1)/2=1.5
- y2 = (4/3 + 3/2)/2 = 1.4166, etc.
Conclusion
- The Pythagorean constant is sometimes known as 2.
- It is commonly used to indicate the diagonal of a one-unit square.
- The number 2 is an irrational number.
- It has a non-terminating and non-repeating decimal.
