I really need help, anyone there?
Prime Factorization is finding which prime numbers multiply together to make the original number.
2³ ∙ 4 ∙ 5 isn't a prime factorization because 4 = 2 ∙ 2 = 2²
In this case prime factorization is:
2³ ∙ 4 ∙ 5 = 2³ ∙ 2 ∙ 2 ∙ 5 = 2³ ∙ 2² ∙ 5 = 2³ ⁺ ² ∙ 5 = 2⁵ ∙ 5
2³ ∙ 4 ∙ 5 isn't a prime factorization because 4 = 2 ∙ 2 = 2²
In this case prime factorization is:
2³ ∙ 4 ∙ 5 = 2³ ∙ 2 ∙ 2 ∙ 5 = 2³ ∙ 2² ∙ 5 = 2³ ⁺ ² ∙ 5 = 2⁵ ∙ 5
