Answer 1

Answer:

2

Step-by-step explanation:

(i)

Let us find the prime factors of 22050 using prime factorization method.

22050 = 2 * 3 * 3 * 5 * 5 * 7 * 7

(ii)

Here we find 2 does not occur in pair.

Therefore, 22050 is not a perfect square.

If we divide 22050 by 2, then

22050 ÷ 2 = 11025

Now,

√11025 = 105 * 105{Perfect square}

Therefore, the least number is 2.

Hope it helps!
