Square Root of 1

The square root of 1 is ±1.  Basically, finding the square root is just the inverse of squaring a number and hence, squaring 1 will result in 1.  The square root of 1 is written as √1 in radical form. In exponential form, it is written as (1)^1/2
 

We can find the square root of 1 through various methods. They are:

• Prime factorization method

• Long division method

• Repeated subtraction method
   

The prime factorization of 1 can be found by dividing the number by prime numbers and continuing to divide the quotients until they can’t be divided anymore.

Find the factors of 1.

So, 1 is already a prime number. Since there is no factor of 1, the square root is directly 1.
 

This is a method 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 too sometimes.

Follow the steps to calculate the square root of 1:

Step 1: Write the number 1 and draw a bar above the pair of digits from right to left.

 1 is a 1-digit number, so just simply draw a bar above it.

Step 2: Now, find the greatest number whose square is less than or equal to 1. Here, it is 1 because 1²=1

Step 3: Now divide 1 by 1 (the number we got from step 2) and we get a remainder 0.

 Step 4: The quotient obtained is the square root. In this case, it is 1.

We know that the sum of first n odd numbers is n2. We will use this fact to find square roots through repeated subtraction method. Likewise, we just have to subtract consecutive odd numbers from the given number, starting from 1. The square root of the given number will be the count of number of steps required to obtain 0.

 Here are the steps:

1−1=0 So, after one subtraction, you're at zero, meaning the square root is 1
 

• Exponential form:  An algebraic expression that includes an exponent. It is a way of expressing the numbers raised to some power of their factors. It includes continuous multiplication involving base and exponent. Ex: 2 × 2 ×2 × 2 = 16 Or, 2 4 = 16, where 2 is the base, 4 is the exponent.

• Prime Factorization: Expressing the given expression as a product of its factors. Ex: 48=2 × 2 × 2 × 2 × 3

• Prime Numbers: Numbers which are greater than 1, having only 2 factors as →1 and Itself. Ex: 1,3,5,7,....

• Rational numbers and Irrational numbers: The Number which can be expressed as p/q, where p and q are integers and q not equal to 0 are called Rational numbers. Numbers which cannot be expressed as p/q, where p and q are integers and q not equal to 0 are called Irrational numbers. 

• Perfect and non-perfect square numbers: Perfect square numbers are those numbers whose square roots do not include decimal places. Ex: 4,9,25 Non-perfect square numbers are those numbers whose square roots comprise decimal places. Ex :3, 8, 24

• Imaginary numbers:  It is the product of a real number and the imaginary unit “i”, where i is defined as i²= -1.
