The prime factorization of 84 can be found by dividing the number by its prime factors:
- Divide by 2: \( 84 \div 2 = 42 \)
- Divide by 2: \( 42 \div 2 = 21 \)
- Divide by 3: \( 21 \div 3 = 7 \)
- 7 is a prime number.
So, the prime factorization of 84 is \( 2^2 \cdot 3^1 \cdot 7^1 \).
Expressing this in the context of your given options, the correct response would be:
\( 2^2 \cdot 3 \cdot 7 \)
