Introduction

Prime factorization is a fundamental concept in mathematics that involves breaking down a composite number into its prime factors. In this article, we will explore the prime factorization of 72, a number that has been a subject of interest in mathematics for centuries. We will examine the different options available and determine the correct prime factorization of 72.

What is Prime Factorization?

Prime factorization is the process of expressing a composite number as a product of its prime factors. A prime factor is a prime number that can be multiplied together to give the original number. For example, the prime factorization of 6 is 2 x 3, because 2 and 3 are prime numbers that can be multiplied together to give 6.

The Options

We have four options available for the prime factorization of 72:

A. $2^2 \times 3^2$ B. $2^2 \times 3^3$ C. $2^3 \times 3^2$ D. $2^3 \times 3^3$

Analyzing the Options

To determine the correct prime factorization of 72, we need to analyze each option carefully. Let's start by examining option A: $2^2 \times 3^2$. This option suggests that 72 can be expressed as the product of two prime numbers, 2 and 3, each raised to the power of 2. To verify this option, we can multiply 2 and 3 together, each raised to the power of 2, and see if we get 72.

$$2^2 \times 3^2 = 4 \times 9 = 36$$

As we can see, option A is incorrect, because 36 is not equal to 72.

Option B: $2^2 \times 3^3$

Next, let's examine option B: $2^2 \times 3^3$. This option suggests that 72 can be expressed as the product of two prime numbers, 2 and 3, each raised to a different power. To verify this option, we can multiply 2 and 3 together, each raised to the power of 2 and 3, and see if we get 72.

$$2^2 \times 3^3 = 4 \times 27 = 108$$

As we can see, option B is also incorrect, because 108 is not equal to 72.

Option C: $2^3 \times 3^2$

Now, let's examine option C: $2^3 \times 3^2$. This option suggests that 72 can be expressed as the product of two prime numbers, 2 and 3, each raised to a different power. To verify this option, we can multiply 2 and 3 together, each raised to the power of 3 and 2, and see if we get 72.

$$2^3 \times 3^2 = 8 \times 9 = 72$$

As we can see, option C is correct, because 72 is equal to 8 x 9.

Option D: $2^3 \times 3^3$

Finally, let's examine option D: $2^3 \times 3^3$. This option suggests that 72 can be expressed as the product of two prime numbers, 2 and 3, each raised to the power of 3. To verify this option, we can multiply 2 and 3 together, each raised to the power of 3, and see if we get 72.

$$2^3 \times 3^3 = 8 \times 27 = 216$$

As we can see, option D is incorrect, because 216 is not equal to 72.

Conclusion

In conclusion, the prime factorization of 72 is $2^3 \times 3^2$. This option is correct, because 72 is equal to 8 x 9. We can verify this option by multiplying 2 and 3 together, each raised to the power of 3 and 2, and see if we get 72.

Introduction

Prime factorization is a fundamental concept in mathematics that involves breaking down a composite number into its prime factors. In this article, we will answer some of the most frequently asked questions about prime factorization.

Q: What is prime factorization?

A: Prime factorization is the process of expressing a composite number as a product of its prime factors. A prime factor is a prime number that can be multiplied together to give the original number.

Q: Why is prime factorization important?

A: Prime factorization is important because it allows us to break down complex numbers into their prime factors. This can be useful in a variety of applications, such as cryptography, coding theory, and number theory.

Q: How do I find the prime factorization of a number?

A: To find the prime factorization of a number, you can use the following steps:

1. Start by dividing the number by the smallest prime number, which is 2.
2. If the number is divisible by 2, continue dividing it by 2 until it is no longer divisible.
3. Once the number is no longer divisible by 2, move on to the next prime number, which is 3.
4. Continue dividing the number by 3 until it is no longer divisible.
5. Repeat this process with the next prime numbers, which are 5, 7, 11, and so on.

Q: What is the difference between prime factorization and factoring?

A: Prime factorization and factoring are both used to break down a composite number into its factors. However, prime factorization involves breaking down the number into its prime factors, whereas factoring involves breaking down the number into any factors, regardless of whether they are prime or not.
