Question

Find the cube root of each of the following numbers by prime factorisation method.

Answer 1

Answer:

4, 8, 22, 30 just factor the numbers

Answer 2

Answer:

i) 4, ii) 8, iii) 22, iv) 30

Step-by-step explanation:

Prime factorisation involves taking out factors of each number that are prime so for example 64 can be factored by

64 = 2 × 32

32 = 2 × 16

16 = 2 × 8

8 = 2 × 4

4 = 2 × 2
