What is The Square Root of 69?

  • The square root of 69 is written as √69 in radical form which is equal to8.30662 (approximately).
  • The number 69 only has two prime factors that are, 3 and 23. So, its square root cannot be simplified further using prime factorization.
  • The square root of 69 can be written as (69)1/2 in exponentialform.

Is Square Root of 69 Rational or Irrational?

The square root of 69 is a non-repeating and non-terminating number so, it cannot be expressed in the form of p/q where q ≠ 0.
Hence, the square root of 69 is an irrational number.

How to Find the Square Root of 69?

We will now find the square root of 69 using the below-given methods:

Square Root of 69 Using Approximation Method

  • Firstly, find two consecutive perfect squares such that 69 lies between them. The two numbers are 64 (82) and 81 (92). So, the whole number part of the square root of 69 will be 8.
  • Now, for determining the decimal part we use the formula: (Given number – Smaller perfect square) / (Greater perfect square – smaller perfect square) = (69 – 64)/(81 – 64) = 5/17 = 0.294
  • Hence, the approx. the square root of 69 by the approximation method is 8.294.

Square Root of 69 By Long Division

Now we will calculate the square root of 69 by the long division method.

  • Start pairing the digits from the unit’s place in pairs of two by putting a bar on top of them. We will have one pair in this case (69).
  • Find a number(a) such that a × a ≤ 69. So, a will be 8 as 8 × 8 = 64.
  • We get the remainder as 5 (69-64) and the quotient as 8. Now, we will add the divisor awith itself and get the new divisor (16).
  • Put a decimal in the dividend and quotient simultaneously. Also, place 3 pairs of zero in the dividend part after the decimal.
  • Bring down one pair of zero. So, our new dividend is 500. Find a number(n) such that 16n × n ≤ 500. The number nwill be 3 as 163 × 3 = 489 ≤ 500.
  • Repeat the above step for the remaining pairs of zero.

Square Root of 69 Solved Examples

  1. Example 1:Mike wants to find out the square root of -69. Can you help Mike?

    Solution:

    The square root of all negative numbers is an imaginary number. So, the square of -69 is represented as √-69 = ±8.306i. (where i = √-1).

  2. Example 2:How much minimum area in square feet should be added in a field of surface area 69 square feet, such that it can be converted into a field of square shape with its length as an integer?

    Solution:
    To convert the field into square-shaped its surface area should be a perfect square. Then the length of the field will be an integer. The nearest perfect square greater than 69 is 81. Therefore, the area of the field that should be added is 81 – 69 = 12 square feet.
