Question

Latoya created a factor tree and wrote the prime factorization of 90 shown below.
A factor tree of 90. 90 branches to 9 and 10. 9 branches to 3 and 3. 10 branches to 2 and 5. The equation is 90 = 2 times 3 times 5.
What is Latoya’s error?
She should not have found the factors of 9.
She should have included an exponent of 2 on the 3.
She should have included 9 and 10 in the prime factorization.
She should have started the tree with 2 times 45.

    Answer:

    She should have included an exponent of 2 on the 3

    Step-by-step explanation:

    The factor tree can be presented as follows;

                    {}                                90

    {}                                                  ↓

    {}                                     9          ↔            10

    {}                                     ↓                           ↓

    {}                                3  ↔  3                  2  ↔  5

    Therefore, the prime factorization of 90 is equal to 90 = 3 × 3 × 2 × 5

    She should have wrote, 90 = 3² × 2 × 5

    Therefore, the error is that she should have included an exponent of 2 on the 3.
