Ex 6.3, 6 For each of the following numbers, find the smallest whole number by which it should be divided so as to get a perfect square. Also find the square root of the square number so obtained. (ii) 2925Prime factorizing 2925 We see that , 2925 = 3 × 3 × 5 × 5 × 13 Since 13 does not occur in pairs, we divide by 13 to make it a pair So, our number becomes 2925 × 𝟏/𝟏𝟑 = 3 × 3 × 5 × 5 × 13 × 𝟏/𝟏𝟑 225 = 3 × 3 × 5 × 5 Square root of 225 :- ∴ √225 = 3 × 5 = 15 ∴ The smallest whole number to be divided = 13 and square root of new number = 15
