give me the answers step by step​

Answer 1

Step-by-step explanation:

(i) By prime factorization of 396, we get

396 = 2 x 2 x 3 x 3 x 11

Here, 2 and 3 are in pair, but 11 does not occur in pair. Hence, the given number is not a perfect square.

Thus, 396 needs to be divided by 11 to become a perfect square.

396/11 = 2 x 2 x 3 x 3 x 11/11

 36 = (2×2) × (3×3)

Thus, 36 has 2 pairs of equal prime factors. Hence, 36 is a perfect square & √36 = 2×3 = 6

Thus, the required smallest whole number by which it should be divided so as to get a perfect square number is 11 and the square root is √36 = 6.
