Square root of 194
Let’s discuss what is a square root? The square root of a number is a number, when multiplied by itself gives the number. Radical symbol (√) is the symbol used to indicate square root. The square root of 25 is ±5. We use it in our daily life in physics, engineering, finance etc.
What is the square root of 194
In this article, the square root of 194 is ±132.92. The square root of 194 is expressed as √194, in radical form. It is expressed as (194)½ in exponential form.
Finding the square root of 194
If a student wants to find the square root of a number. Which are the methods they can use? Some common methods are,
- Prime factorization
- Long division
- Approximation
- Subtraction method
Let’s check the square root of 194 using these methods
Square root of 194 by prime factorization
In this method, all the prime factors of the number are listed down and then from there one number from each pair is listed down. Then the numbers are multiplied together.
By using prime factorization, let’s check out the square root of 194.
Step 1: Listing out the prime factors of 194 and pairing the same numbers.
Prime factors of 194 = 2 × 97
As 194 has no pair of prime numbers so, the prime factorization method is not applicable for the square root of 194
Square root of 194 by long division
Here, the given number is divided into smaller numbers to find the square root of the number.
Using the long division method, let’s check the square root of 194
Step 1: The number given, 194 has three digits so let’s pair that number. Here it is 1 and 75.
Finding the number whose square is less than or equal to the 1
Here the number is, because 12 = 1
Step 2: So, let’s divide 1 by 1
Step 3: Now, the quotient and divisor is 1, for the new divisor we add the divisor with itself.
Step 4: Continue the process till the remainder is 0
The quotient will be the square root of the number.
Therefore, the square root of 194 is ±13.45
Square root of 194 by approximation
Approximation method is mainly used for not a perfect square. As 194 is not a perfect square, the approximation method can be used to find the square root of 194.
Step 1: Find any two perfect squares numbers between which 194 lies. The two perfect squares are 132 (169) and 142 (196)
Therefore, the square root of 194 lies between 13 and 14, i.e, 13 < √194 <14
Step 2: for checking out the decimal part, the formula is
Hence,194 - 169 / 196 - 169 = 25 / 27 = 0.925
So, the approximate square of 194 is ±13.925
Square root of 194 by subtraction method
In the subtraction method, based on the fact, the sum of the first n odd number is n2. So, here the given number is subtracted with the odd number starting with 1. The process will go on till the given number becomes 0. The method is mainly used for perfect squares; it is not used to find the square root of 194.
Common errors and how to avoid them in the square root of 194
Students tend to make errors while finding the square root of a number. So, let’s check some common errors while finding the square root and the ways to avoid it
Mistake 1
Errors while counting the prime factors
Students tend to make errors in the prime factorization method by making errors in counting. To avoid it, make sure to recount each factor. And make sure to verify the answer.
