Answer 2

Answer:

1. 3
2. 2
3. 9
4. 11

(i) 81 = 3*3*3*3 = (3³ × 3)

so , for making it perfect cube , 81 should be divided by 3

(ii) 128 = 2*2*2*2*2*2*2 = (2³×2³×2)

=> 128 = (4³×2)

so ,for making it perfect cube, 128 should be divided by 2

(iii) 72 = (2*2*2*3*3)

=> 72 = (2³×9)

so for making it perfect cube,72 should be divided by 9

(iv) 704 = (2*2*2*2*2*2*11) = (2³×2³×11)

=> 704 = (4³×11)

so, for making it perfect cube, 704 should be divided by 11
