Question

for finding the cube root of a perfect cube
1. resolve the given numbers into prime factors
2. make triplets of identical factors
3. choosing one factor from each triplet, take product of those prime factors ​

Answer 1

Answer:

The answer has to be the first one

Step-by-step explanation:

For example, let's take 27 which is a perfect cube and in order to find the cube root, what I prefer is to do prime factorisation. That way you get the number required.

For 27, the answer would be 3 and for 64, its 4 and so on. Hope this helps.

Answer 2

Answer:

Begin by prime-factorizing the given number. Then, divide it by the extra prime factors, i.e. those that do not form a triplet.
