Answer:
She should have included an exponent of 2 on the 3
Step-by-step explanation:
The factor tree can be presented as follows;
        [tex]{}[/tex]                 90
[tex]{}[/tex]                          ↓
[tex]{}[/tex]                   9      ↔       10
[tex]{}[/tex]                   ↓              ↓
[tex]{}[/tex]                 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.
