Square root of 300

The square root is a number that, when multiplied by itself, results in the original number whose square root is to be found. Know that the square root of 300 is ±17.3205080757.

We will see here more about the square root of 300. As defined, the square root is just the opposite (inverse) of squaring a number, so, squaring 17.3205… will result in 300. The positive value, 17.3205… is the solution of the equation x² = 300.

It contains both positive and a negative root, where the positive root is called the principal square root. The square root of 300 is expressed as √300 in radical form. In exponential form, it is written as (300)^1/2  .

The simplest radical form of √300 is 10√3. We will see how to obtain the simplest radical form further in this article.
We now came to a point where we can say that:

• 300 is a non-perfect square.
•  
• √300 is an irrational number.
   

Let us now find how we got this value of 17.3205… as a square root of 300.

We will use these methods below to find.

•  Prime factorization method

•  Long division method

• Approximation/Estimation method

The prime factorization of 300 involves breaking down a number into its factors.

Factorize 300 by prime numbers, and continue to divide the quotients until they can’t be separated anymore. 

• Find the prime factors of 300.

• After factoring 300, make pairs out of the factors to get the square root.

•  If there exist numbers that cannot be made pairs further, we place those numbers with a “radical” sign along with the obtained pairs.

Prime factorization of 300 = 3×2×2×5×5

For 300, two pairs of factors 2 and 3 are obtained, but a single 3 is remaining.

So, it can be expressed as √300 = √(3×2×2×5×5) = 2×5√3 = 10√3.

10√3 is the simplest radical form of √300.
 

Long Division method is used for obtaining the square root for non-perfect squares, mainly. It usually involves the division of the dividend by the divisor, getting a quotient and a remainder for non-perfect squares. To make it simple it is operated on divide, multiply, subtract, bring down and do-again.

To calculate the square root of 300:

Step 1: On the number 300.000000, draw a horizontal bar above the pair of digits from right to left.

Step 2: Find the greatest number whose square is less than or equal to 3. Here, it is 1, Because 1²=1 < 3.

Step 3 : Now divide 3 by 1 such that we get 1 as a quotient and then multiply the divisor with the quotient, we get 1.

Step 4: Subtract 1 from 3. Bring down both the 0 and place it beside the difference 2.

Step 5: Add 1 to the same divisor, 1. We get 2.

Step 6: Now choose a number such that when placed at the end of 2, a 2-digit number will be formed. Multiply that particular number by the resultant number to get a number less than 200. Here, that number is 7. 

27×7=189<200. In quotient’s place, we also place that 7.

Step 7: Subtract 200-189=11.

 Add a decimal point after the new quotient 17, again, bring down two zeroes and make 11 as 1100. Simultaneously add the unit’s place digit of 27, i.e., 7 with 27. We got here, 34. Apply Step 5 again and again until you reach 0. 
We will show two places of precision here, and so, we are left with the remainder, 7100 (refer to the picture), after some iterations and keeping the division till here, at this point 

             
Step 8 : The quotient obtained is the square root. In this case, it is 17.32….
 

Estimation of square root is not the exact square root, but it is an estimate, or you can consider it as a guess.

Follow the steps below:

Step 1: Find the nearest perfect square number to 300. Here, it is 289 and 324.

Step 2: We know that, √289=±17 and √324=±18. This implies that √300 lies between 17 and 18.

Step 3: Now we need to check √300 is closer to 17 or 17.5. Since (17)²=289 and (17.5)²=306.25. Thus, √300 lies between 17 and 17.5.

Step 4: Again considering precisely, we see that  √300 lies close to (17.5)²=306.25. Find squares of (17.2)²=295.84 and (17.4)²= 302.76.

We can iterate the process and check between the squares of 17.3 and 17.39 and so on.

We observe that √300 = 17.32…
