To find the prime factorization of 84, we can start by dividing it by the smallest prime numbers and continue the process.
1. 84 is even, so we divide by 2:
\( 84 \div 2 = 42 \)
2. 42 is also even, so we divide by 2 again:
\( 42 \div 2 = 21 \)
3. 21 is divisible by 3:
\( 21 \div 3 = 7 \)
4. 7 is a prime number.
Now, we can write the prime factorization of 84 as:
- \( 2^2 \times 3 \times 7 \)
So, the correct option is:
**2 squared times 3 times 7**.
