What is the Square Root of 1/4?

The square root is the inverse of the square of a number. 1/4 is a perfect square. The square root of 1/4 is expressed in both radical and exponential form. In the radical form, it is expressed as √(1/4), whereas (1/4)^(1/2) in the exponential form. √(1/4) = 1/2, which is a rational number because it can be expressed in the form of p/q, where p and q are integers and q ≠ 0.

Finding the Square Root of 1/4

The process of finding square roots can vary depending on whether the number is a perfect square or not. For 1/4, which is a perfect square, simple arithmetic can be used. Let us now explore the following methods:

 

  • Arithmetic method
  • Prime factorization method
  • Long division method

Square Root of 1/4 by Arithmetic Method

Since 1/4 is a perfect square, we can find its square root using simple arithmetic. The square root of a fraction is the square root of the numerator divided by the square root of the denominator.

 

Step 1: The numerator is 1, and the square root of 1 is 1.

 

Step 2: The denominator is 4, and the square root of 4 is 2.

 

Step 3: Therefore, the square root of 1/4 is 1/2.

Square Root of 1/4 by Prime Factorization Method

The prime factorization method can be used to understand the structure of a number, even though it is not necessary for simple fractions like 1/4.

 

Step 1: The prime factorization of 1 is trivial as it is self-contained, and 4 can be expressed as 2 x 2.

 

Step 2: To find the square root, we pair the prime factors of the denominator. Since 4 = 2 x 2, its square root is 2.

 

Step 3: The square root of 1 is 1, so the square root of 1/4 is 1/2.

Square Root of 1/4 by Long Division Method

While the long division method is typically used for more complex numbers, it can also be applied here to illustrate the process.

 

Step 1: The fraction 1/4 can be converted to a decimal, 0.25.

 

Step 2: Use the long division method to find the square root of 0.25.

 

Step 3: Pair 25 as 0.25 and find a number whose square is close to 25.

 

Step 4: The number is 5 because 5 x 5 = 25.

 

Step 5: Therefore, the square root of 0.25 is 0.5, which corresponds to 1/2 in fractional form.
