A rational number is a number that is of the form p/q where p and q are integers and q is not equal to 0. A number that cannot be expressed as a ratio of two integers is an irrational number. Non-terminating decimals having repeated numbers after the decimal point are rational numbers. √28 = 5.291502322…

Simplified Radical Form of Square Root of 27

To simplify the square root of 28, let us first express 28 as a product of its prime factors. Prime factorization of 28 is 2 × 2 × 7. Therefore, √28 can be simplified further as √(2 × 2 × 7) =2√7. Thus, we have expressed the square root of 28 in the simplest radical form as 2√7.

Square Root of 27 by Long Division Method

Follow the steps given below to find the square root of 28 by long division.

Step 1: We group the digits 2 and 8 into a pair by placing a bar over it. Since our number is 28, let us represent it as inside the division symbol.
Step 2: We find the largest number such that when you multiply it with itself, the product is less than or equal to 28. We know that 5 × 5 = 25 as 25 < 28.
Step 3: Let us place a decimal point and zero pairs and continue our division. Now, multiply the quotient by 2 and the product becomes the starting digit of our next divisor.
Step 4: Choose the largest number in the unit’s place for the new divisor such that its product with a number is less than or equal to 300. We know that 0 is in the ten’s place and our product has to be 204 and the closest multiplication is 102 × 2 = 204. Therefore, use the number 2 in the unit place which gives 102 × 2 = 204.
Step 5: Bring down the next pair of zeros and multiply the quotient 52 (ignore the decimal) by 2, which is 104, and the starting digit of the new divisor. Note that the square root of 28 is an irrational number, i.e., it is never-ending. So, stop the process after 2 or 3 more iterations by repeating steps 3 and 4, and you have the square root of 28 by the long division method.
