What is the Square Root of 185?
- The square root of 185 in decimal form is 13.6014.
- The square root of 185 can be written as (185)1/2 in exponential form.
- The square root of 185 is written as √185 in radical form.
- The number 185 only has two prime factors that are, 5 and 37. Hence, its square root cannot be simplified further using the prime factorization.
Is Square Root of 185 Rational or Irrational?
The square root of 185 is a non-repeating and non-terminating number. A number is called a rational number when it can be expressed in the form of p/q where q ≠ 0 hence, the square root of 185 is an irrational number.
How to Find the Square Root of 185?
We will now find the square root of 185 using the below-given methods:
- Square Root of 185 Using Approximation Method
- Square Root of 185 by Long Division
Square Root of 185 Using Approximation Method
- Firstly, find two consecutive perfect squares such that 185 lies between them. The two perfect squares are 169 (132) and 196 (142). So, the whole number part of the square root of 185 will be 13.
- To determine the decimal part we use the formula: (Given number - smaller perfect square) / (Greater perfect square - smaller perfect square)
= (185 - 169)/(196 - 169) = 16/27 = 0.592 - So, the approx. the square root of 185 by the approximation method is 13.592.
Square Root of 185 By Long Division
Now we will calculate the square root of 185 by the long division method.
- Start pairing the digits by drawing a line on top of them from the unit’s place in pairs of two. We will have two pairs in this case (1 & 85).
- Find a number(a) such that a × a ≤ 1. So, a will be 1 as 1 × 1 = 1.
- We get the quotient as 1. Now, we will add the divisor a with itself and get the new divisor (2). Bring the next pair down (85). So, the dividend becomes 085.
- Now, find a number(y) such that 2y × y ≤ 85. The number y will be 3 as 23 × 3 = 69 ≤ 85.
- Put a decimal after the dividend and quotient simultaneously. Also, place 3 pairs of zero in the dividend part after the decimal (185. 00 00 00) and repeat the above step for the remaining three pair of zero.
So, we get the square root of √185 = 13.601 by the long division method.

Square Root of 185 Solved Examples
-
Example 1: Help Derick determine the %error in the square root of 185 calculated by the approximation method and analyze whether it is over or underestimated.
Solution:
The value of the square root of 185 is √185 = 13.601.
The value of the square root of 185 calculated by approximation method is √185 = 13.592.
As the value is less than the actual value so, it is underestimated.
Now, % error = ((13.601 – 13.592)/13.601) × 100 = 0.066%
Hence, the %error in the square root of 185 calculated by the approximation method is 0.066%. -
Example 2: A car is covering √185 miles per 5 mins. What is the speed of the car in miles/hour?
Solution:
Speed of car in miles/min = (Distance/Time) = √185/5 = √37/√5 Miles/min.
Now, speed of the car in miles/hr = speed of the car in miles/min × 60 = (√37/√5) × 60
On simplifying we get, √37 × 12√5 = 12√185 = 12 × 13.60 = 163.2 miles/hour.
