Square Root of 16/49 by Prime Factorization Method

The product of prime factors is the prime factorization of a number. Now let us look at how 16/49 is broken down into its prime factors.

 

Step 1: Finding the prime factors of 16 and 49. For 16, the prime factors are 2 x 2 x 2 x 2 = 2^4. For 49, the prime factors are 7 x 7 = 7^2.

 

Step 2: Now we found out the prime factors. The square root of 16/49 is √(2^4/7^2) = (2^2/7) = 4/7.

Square Root of 16/49 Examples

Ray, the Character from BrightChamps Explaining Math Concepts

Problem 1

Can you help Max find the area of a square box if its side length is given as √(16/49)?

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

The area of the square is 16/49 square units.

Explanation

The area of the square = side².

The side length is given as √(16/49).

Area of the square = side² = (4/7) × (4/7) = 16/49.

Therefore, the area of the square box is 16/49 square units.

Problem 2

A square-shaped building measuring 16/49 square feet is built; if each of the sides is √(16/49), what will be the square feet of half of the building?

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

8/49 square feet

Explanation

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

Dividing 16/49 by 2 = 8/49.

So half of the building measures 8/49 square feet.

Problem 3

Calculate √(16/49) × 5.

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

20/7

Explanation

The first step is to find the square root of 16/49, which is 4/7.

The second step is to multiply 4/7 by 5.

So (4/7) × 5 = 20/7.

Problem 4

What will be the square root of (16/49 + 1)?

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

The square root is 8/7.

Explanation

To find the square root, we need to find the sum of (16/49 + 1).

16/49 + 49/49 = 65/49, and then √(65/49) = 8/7.

Therefore, the square root of (16/49 + 1) is 8/7.

Problem 5

Find the perimeter of the rectangle if its length ‘l’ is √(16/49) units and the width ‘w’ is 38 units.

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

The perimeter of the rectangle is 76 + 8/7 units.

Explanation

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

Perimeter = 2 × (√(16/49) + 38) = 2 × (4/7 + 38) = 2 × (4/7 + 266/7) = 2 × 270/7 = 540/7 = 76 + 8/7 units.
