Simplify: $\sqrt{\frac{576}{64}}$ - A Step-by-Step Guide to Prime Factorization and Simplifying Radical Expressions

In mathematics, simplifying radical expressions is an essential skill that helps us to solve problems more efficiently and accurately. One of the most common methods of simplifying radical expressions is by using prime factorization. In this article, we will explore how to simplify the expression $\sqrt{\frac{576}{64}}$ using prime factorization and other techniques.

The Prime Factorization of 576

To simplify the expression $\sqrt{\frac{576}{64}}$ , we need to find the prime factorization of both 576 and 64. The prime factorization of a number is the expression of that number as the product of its prime factors.

The prime factorization of 576 is:

576 = 2^6 \times 3^2

As we can see, the prime factorization of 576 is $2^6 \times 3^2$ . This means that 576 can be expressed as the product of two prime numbers, 2 and 3, raised to certain powers.

The Prime Factorization of 64

Similarly, we need to find the prime factorization of 64.

The prime factorization of 64 is:

64 = 2^6

As we can see, the prime factorization of 64 is $2^6$ . This means that 64 can be expressed as the product of the prime number 2 raised to the power of 6.

Simplifying the Expression $\sqrt{\frac{576}{64}}$

Now that we have found the prime factorization of both 576 and 64, we can simplify the expression $\sqrt{\frac{576}{64}}$ .

We can start by simplifying the fraction inside the square root:

\frac{576}{64} = \frac{2^6 \times 3^2}{2^6}

As we can see, the $2^6$ terms cancel out, leaving us with:

\frac{576}{64} = 3^2

Now, we can take the square root of both sides:

\sqrt{\frac{576}{64}} = \sqrt{3^2}

As we know, the square root of a perfect square is equal to the number itself. Therefore, we can simplify the expression as follows:

\sqrt{\frac{576}{64}} = 3

In this article, we have learned how to simplify the expression $\sqrt{\frac{576}{64}}$ using prime factorization and other techniques. We have seen how to find the prime factorization of both 576 and 64, and how to simplify the fraction inside the square root. Finally, we have taken the square root of both sides to get the simplified expression.

When simplifying radical expressions, it is essential to find the prime factorization of both numbers.
Use the properties of exponents to simplify the expression.
Take the square root of both sides to get the simplified expression.
