What Is the Square Root of 841?
√841 = 29
The answer which we get on squaring 29² is 841. This makes 841 a perfect square.
Is the Square Root of 841 Rational or Irrational?
A rational number can be either terminating or non-terminating and has a repeating pattern in its decimal part. We saw that √841 = 29. 29 is a whole number. It is possible to express it in p/q form easily. Hence, √841 is a rational number.
How to Find the Square Root of 841?
There are different methods to find the square root of any number. Click here to know more about it.
The factors of 841 are 1, 29, and 841.
As 841 has more than 2 factors, it is a composite number
To find the square root of 841:
- We can use prime factorization method to obtain one number from each pair of the same numbers and multiply them. The prime factorization of 841 is 29 × 29 which consists of 1 pair of the same number, 29. Thus, the square root of 841 = 29.
- Since 841 is a perfect square, we can also express it as 292. The number within square root which gets repeated is √(29 × 29) = 29. Hence, the square root of 841 is 29.
√841 = √29² = (29)2 × ½ = 29
The square root of 841 is 29.

Square Root of 841 Solved Examples
Example 1: What is the difference in lengths of square boxes having area 841 square inches and 729 square inches ?
As the area of square box is area = length × length
The length of square box having area 841 square inches is √841 = 29 inches.
Similarly the length of box having area 729 square inches is √729 = 27 inches.
The difference in lengths of boxes is (29 - 27) inches = 2 inches
Hence, the difference in length of square boxes having area 841 square inches and 729 square inches is 2 inches.
Example 2: Can you determine the radius of circle having area 841π square inches?
Radius can be found using the formula of area of a circle is πr2 square inches. By the given information,
πr2 = 841π
r2 = 841
By taking the square root on both sides we get, √r2= √841. We know that the square root of r2 is r.
By calculating the square root of 841 is 29 inches.
Example 3: Can you determine the square root of 841 using long division method?
To find the square root of 841 using long division method we need to follow the following steps:
- Step1. Write 841 as shown in the figure. Start pairing the digits from the right end in pairs of two by putting a bar on top of them. So, we got two pairs of 8 and 41
- Step2. Now find a number (q) such that q × q is a number less than equal to 8. Hence, q = 2 (2 × 2 = 4).
- Step3. Now subtract the obtained value from the first pair in the dividend and add the divisor with itself (q + q) (2 + 2 = 4). Now bring the second pair down (41). The remiander is 441.
- Step4. Now find a number (p) such that 2p × p is less than equal to 441. Here m will be 9 as 49 × 9 = 441.
