Understanding the Problem

When dealing with the product of two numbers that involve square roots, it's essential to understand the properties of radicals and how they interact with multiplication. The product of two numbers in the form of $$a\sqrt{b}$$ and $$c\sqrt{d}$$ can be found by multiplying the coefficients (a and c) and then multiplying the radicands (b and d). However, if the radicands have any common factors, we can simplify the expression by taking the square root of the product of these factors.

Breaking Down the Problem

To find the product of $$6 \sqrt{12}$$ and $$2 \sqrt{14}$$, we need to multiply the coefficients (6 and 2) and then multiply the radicands (12 and 14). We can start by breaking down the radicands into their prime factors.

Prime Factorization of Radicands

The prime factorization of 12 is $$2^2 \cdot 3$$.
The prime factorization of 14 is $$2 \cdot 7$$.

Multiplying the Coefficients and Radicands

Now that we have the prime factorizations of the radicands, we can multiply the coefficients and then multiply the radicands.

Multiplying the Coefficients

The product of the coefficients is $$6 \cdot 2 = 12$$.

Multiplying the Radicands

To multiply the radicands, we need to multiply the prime factors. We can do this by multiplying the exponents of the common prime factors and then multiplying the remaining prime factors.

The product of the prime factors of 12 and 14 is $$2^3 \cdot 3 \cdot 7$$.
Since the radicands have a common factor of 2, we can simplify the expression by taking the square root of the product of these factors.

Simplifying the Expression

Now that we have the product of the coefficients and the radicands, we can simplify the expression by taking the square root of the product of the common factors.

Simplifying the Radicand

The product of the common factors is $$2^3 = 8$$. We can take the square root of this product to simplify the radicand.

The square root of 8 is $$\sqrt{8} = \sqrt{4 \cdot 2} = 2\sqrt{2}$$.

Final Answer

Now that we have simplified the radicand, we can write the final answer.

Final Answer

The product of $$6 \sqrt{12}$$ and $$2 \sqrt{14}$$ in simplest radical form is $$12 \cdot 2\sqrt{2} \cdot 3 \cdot 7 = 12 \cdot 42 \cdot \sqrt{2} = 504 \sqrt{2}$$.

Conclusion

In this article, we have shown how to find the product of two numbers that involve square roots. We have used the properties of radicals and prime factorization to simplify the expression and find the final answer. The product of $$6 \sqrt{12}$$ and $$2 \sqrt{14}$$ in simplest radical form is $$504 \sqrt{2}$$.

Understanding Radicals and Prime Factorization

Radicals and prime factorization are fundamental concepts in mathematics that are used to simplify complex expressions. In this article, we will answer some frequently asked questions about simplifying radicals and prime factorization.

Q: What is a radical?

A: A radical is a mathematical expression that involves the square root of a number. It is denoted by the symbol √ and is used to represent the positive or negative square root of a number.

Q: What is prime factorization?

A: Prime factorization is the process of breaking down a number into its prime factors. Prime factors are the smallest numbers that can be multiplied together to get the original number.

Q: How do I simplify a radical?

A: To simplify a radical, you need to find the prime factorization of the number inside the radical sign. You can then take out any pairs of prime factors that are squared.
