If the number of odd, even perfect square perfect cube factors of 4500...
Prime Factorization of 4500
To determine the odd, even perfect square, and perfect cube factors of 4500, we first need its prime factorization.
4500 can be factored as follows:
- 4500 = 45 × 100
- 45 = 5 × 9 = 5 × 3²
- 100 = 10² = (2 × 5)² = 2² × 5²
Thus, the complete factorization is:
4500 = 2² × 3² × 5³
Finding Perfect Square Factors
Perfect square factors must have even powers for all prime factors.
- In 2², the even power is 0 or 2.
- In 3², the even power is 0 or 2.
- In 5³, the even power is 0, 2.
Calculating combinations:
- Choices for 2: 2 options (0, 2)
- Choices for 3: 2 options (0, 2)
- Choices for 5: 2 options (0, 2)
Total perfect square factors = 2 × 2 × 2 = 8.
Finding Perfect Cube Factors
Perfect cube factors must have powers that are multiples of 3.
- In 2², the only choice is 0.
- In 3², the only choice is 0.
- In 5³, choices are 0 or 3.
Calculating combinations:
- Choices for 2: 1 option (0)
- Choices for 3: 1 option (0)
- Choices for 5: 2 options (0, 3)
Total perfect cube factors = 1 × 1 × 2 = 2.
Identifying Odd and Even Factors
- Odd perfect square factors: Consider only 3² and 5³. Total = 2 (0, 2 for 3) × 2 (0, 2 for 5) = 4.
- Even perfect square factors: Must include 2². Total = 2 (0, 2 for 2) × 2 (0, 2 for 3) × 2 (0, 2 for 5) = 4.
In summary:
- Odd perfect square factors: 4
- Even perfect square factors: 4
- Perfect cube factors: 2
