Answer 1

Answer:

(i) 18 (ii) 20 (iii) 9 (iv) 5 (v) 1256641 (vi) 100 (vii) 7 (viii) 5 (ix) 11 (x) 14

Step-by-step explanation:

Using prime factorization, I found the smallest numbers needed to make the numbers in your question perfect cube numbers. Hope this helps.

Answer 2

Answer:

Step-by-step explanation:

question no. (3) { 24}

solution = 24

using the prime factorisation method we get 2*2*2*3

since the factors of 3 in 24 is not in a group of 3, it is not a perfect cube.

so, we multiply 24 by 3*3.

also, the smallest number = 3*3

                                           = 9//.
