What is the Square Root of 49/64?

The square root is the inverse of the square of the number. 49/64 is a perfect square fraction. The square root of 49/64 is expressed in both radical and exponential form. In radical form, it is expressed as √(49/64), whereas (49/64)^(1/2) in exponential form. √(49/64) = 7/8, 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 49/64

The prime factorization method works well for perfect square numbers, including fractions. Let's discuss the methods commonly used to find square roots:

 

  • Prime factorization method
  • Long division method
  • Approximation method

Square Root of 49/64 by Prime Factorization Method

The product of prime factors is the prime factorization of a number. Now let us look at how 49/64 is broken down into its prime factors.

 

Step 1: Finding the prime factors of 49 and 64 49 can be factored as 7 x 7 64 can be factored as 2 x 2 x 2 x 2 x 2 x 2

Step 2: Since 49 and 64 are both perfect squares, the square root can be directly obtained by taking the square root of the numerator and the denominator separately. √(49/64) = √49 / √64 = 7/8

Square Root of 49/64 by Long Division Method

The long division method is useful for non-perfect square numbers but can also verify perfect squares. Here is how to find the square root using the long division method, step by step:

 

Step 1: Write the number 49/64 in decimal form, which is 0.765625.

 

Step 2: Start by grouping digits in pairs from right to left in the decimal.

 

Step 3: Find the largest integer whose square is less than or equal to the first group. Here, the first group is 0.76, and 0.8 works because 0.8 x 0.8 = 0.64.

 

Step 4: Subtract, bring down the next group, and repeat the process for each pair.

 

Step 5: Continue the process until you reach an accurate value. For 0.765625, the square root is exactly 0.875, which confirms our previous result.

Square Root of 49/64 by Approximation Method

Approximation method is another method for finding square roots and is useful for non-perfect squares. However, for fractions like 49/64, we can directly find an exact result:

 

Step 1: Identify closest perfect squares for the numerator and the denominator.

Step 2: Since 49 and 64 are perfect squares, this method confirms that √49 = 7 and √64 = 8. Thus, √(49/64) = 7/8, which is an exact result.

Forgetting about the negative square root

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

It is important to remember that a number has both positive and negative square roots. However, we usually take only the positive square root for practical purposes.

 

For example, √(49/64) = 7/8, but there is also -7/8, which should not be forgotten.

Square Root of 49/64 Examples

Ray, the Character from BrightChamps Explaining Math Concepts
Max, the Girl Character from BrightChamps

Problem 1

Can you help Max find the area of a square box if its side length is given as √(49/64)?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The area of the square is 49/64 square units.

Explanation

The area of the square = side².

The side length is given as √(49/64).

Area of the square = (√(49/64))² = 49/64.

Problem 2

A square-shaped building measuring 1 square foot is built; if each of the sides is √(49/64), what will be the square feet of half of the building?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

0.5 square feet

Explanation

We can divide the given area by 2 as the building is square-shaped.

Dividing 1 by 2 = 0.5.

So half of the building measures 0.5 square feet.

Problem 3

Calculate √(49/64) x 5.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

4.375

Explanation

The first step is to find the square root of 49/64, which is 7/8.

The second step is to multiply 7/8 with 5.

So 7/8 x 5 = 4.375.

Problem 4

What will be the square root of (49/64 + 15/64)?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The square root is 1.

Explanation

To find the square root, we need to find the sum of (49/64 + 15/64). 49/64 + 15/64 = 64/64 = 1, and then √1 = 1.

Problem 5

Find the perimeter of the rectangle if its length ‘l’ is √(49/64) units and the width ‘w’ is 5 units.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

We find the perimeter of the rectangle as 10.75 units.

Explanation

Perimeter of the rectangle = 2 × (length + width).

Perimeter = 2 × (7/8 + 5) = 2 × (0.875 + 5) = 2 × 5.875 = 11.75 units.
