Grouping the factors into the pairs of equal factors.
(6.5 × 6.5)
Take one number from each group and multiply them to find the number whose square is 42.25.
6.5.

The square root of 42.25 is 6.5.

2. Evaluate √1.96?

Solution:
Given the number is √1.96,
To find the square root of a perfect square by the prime factorization method, we have to find the factors of 1.96.
1.96 = 1.4 × 1.4
Grouping the factors into the pairs of equal factors.
(1.4 × 1.4)
Take one number from each group and multiply them to find the number whose square is 1.96.
1.4.

The square root of 1.96 is 1.4.

3. Evaluate √39.69?

Solution:
Given the number is √39.69,
To find the square root of a perfect square by the prime factorization method, we have to find the factors of 39.69.
39.69 = 6.3 × 6.3
Grouping the factors into the pairs of equal factors.
(6.3 × 6.3)
Take one number from each group and multiply them to find the number whose square is 39.69.
6.3.

The square root of 39.69 is 6.3.

4. Evaluate √547.56?

Solution:
Given the number is √547.56,
To find the square root of a perfect square by the prime factorization method, we have to find the factors of 547.56.
547.56 = 23.4 × 23.4
Grouping the factors into the pairs of equal factors.
(23.4 × 23.4)
Take one number from each group and multiply them to find the number whose square is 547.56.
23.4.

The square root of 547.56 is 23.4.

5. Evaluate √0.064516?

Solution:
Given the number is √0.064516,
To find the square root of a perfect square by the prime factorization method, we have to find the factors of 0.064516.
0.064516 = 0.254 × 0.254
Grouping the factors into the pairs of equal factors.
(0.254 × 0.254)
Take one number from each group and multiply them to find the number whose square is 0.064516.
0.254.
