Square Root of 1681

The square root of a number is the value which, when multiplied by itself, gives the original number. e.g. 10 × 10 = 100; the square root of 100 is 10. Similarly, 1681 is a perfect square number. The square root of 1681 will be a number whose product with itself will result in 1681. The mathematical operation of square root is the inverse of a square. The square root of a number can be positive or negative, rational or irrational, real or imaginary. In this mini-lesson, we will calculate the square root of 1681 using different methods and we will look at some interesting problems related to it. 1681 is a perfect square number which can be obtained by the square of 41. Hence, the square root of 1681 is a rational number. In this mini-lesson, we will learn to find the square root of 1681 along with solved examples. Let us now find the square root of 1681.

• Square Root of 1681: √1681 = 41
• Square of 1681: 1681^² = 28,25,761

The square root of a number n is written as √n. This number when squared or multiplied by itself results in the original number n. We know that addition has an inverse operation which is subtraction and multiplication has an inverse operation which is division. Similarly, calculating the square root of a number is the inverse operation of squaring that number. The square root of 1681 is the number which, when multiplied to itself, will give the number 1681 as the result. Thus, we need to think of a number whose square is 1681.

• Square root of 1681 is written as √1681 (Radical form)
• Square root of 1681 = √1681 = √(41 × 41) = +41 and -41
• In the exponential form, the square root of 1681 is expressed as (1681)^1/2

The square root of 1681 is 41.

A rational number is a number that can be expressed in the form of p/q. A number that is not a rational number is called an irrational number. Non-terminating decimals which have repeated numbers after the decimal point are rational numbers. Now, let us look at the square root of 1681. 1681 can be broken into two factors which on multiplying give 1681. It can be written as a square of 41, which is a rational number. This shows that 1681 is a perfect square number.

• 1681 is a number that is a perfect square because it has a natural number as its square root.
• Square root of 1681 is 41
• Square root of 1681 can be expressed as a fraction of the form p/q which tells us that the square root of 1681 is a rational number.
• The square root of 1681 is either +41 or -41.
• 41 and -41 can be expressed as 41/1 and -41/1. Both the numbers can be represented in the form of a rational number. Thus, the square root of 1681 is a rational number.

The square root of 1681 can be calculated using different methods such as: prime factorization and long division method. Since 1681 is a perfect square, we can use the repetitive subtraction method as well.

Let us calculate the square root of 1681 using long division method.

Square Root of 1681 by Long Division Method

• Step 1. Write 1681 as shown in the figure. Start grouping the number in pairs from the right. 81 is the first pair from the right and the next pair is 16. 
• Step 2: Find the largest number that when multiplied with itself will give 16 or a smaller number closest to 16. Here it is 4 (4 × 4 = 16, remainder = 0).
• Step 3: Bring down the next pair of numbers. Here it is 81. The new divisor is 81 and the dividend is 81.
• Step 4: Find the largest number that when kept at ones place with 8 at tens place multiplied with that same number gives 81 as the result or a number closest to 81. 
• Step 5: 1 is the next quotient place. Now we get our new divisor as 81 as 81 × 1 = 81. Complete the division and get the remainder. We get 0 as the remainder. Thus, the process of division completes here.

Therefore, the square root of 1681 = 41.
