The square source of 8 is expressed together √8 in the radical kind and together (8)½ or (8)0.5 in the exponent form. The square root of 8 rounded as much as 8 decimal locations is 2.82842712. It is the optimistic solution of the equation x2 = 8. We deserve to express the square root of 8 in its lowest radical kind as 2 √2.

## What Is the Square root of 8?

We recognize that addition has one inverse operation as subtraction and also multiplication has an inverse operation as division. Similarly, recognize the square root is one inverse operation of squaring a number. The square root of 8 gives a number the when multiplied to itself offers the number 8. Hence, we have to think that a number who square is 8.

## Is the Square root of 8 Rational or Irrational?

A reasonable number is a number that can be express in the type of p/q, whereby p and q room integers and q is no equal to 0. A number that is not a reasonable number is called an irrational number. Non-terminating decimals the have repeated numbers after the decimal allude are rational numbers. Now let us look at the square source of 8. The decimal representation of 8 is 2.828427125

Do you think the decimal component stops after ~ 2.828427125?

Hence, the square source of 8 is no a rational number. That is an irrational number.

## How to find the Square source of 8?

We will discuss two techniques to find the square root of 8.

Simplifying the radical of the numbers that are perfect squaresLong department method for perfect and also non-perfect squares

The element factorization that 8 is 8 = 2 × 2 × 2. Therefore, 8 have the right to be simplified further as 8 =(2 × 2 × 2) = 22. Thus, we have expressed the square root of 8 in the simplest radical type as 22

So, 8 = 22

### Square source of 8 by Long division Method

The value of the square source of 8 by long division method is composed of the adhering to steps:

Step 1: starting from the right, we will pair increase the digits by placing a bar over them.Step 2: Find a number that, as soon as multiplied to itself, provides the product much less than or same to 8. So, the number is 2. Maintaining the divisor together 2, we gain the quotient together 2 and the remainder together 4.Step 3: Double the divisor and enter it with a blank on that is right. Guess the largest feasible digit to fill in the empty which will end up being the brand-new digit in the quotient, such that when the new divisor is multiply to the brand-new quotient the resultant product is less than or same to the dividend. Divide and write the remainder. Repeat this process to acquire the decimal places you want.
