Step-by-Step Simplification of $\sqrt{12} \cdot 4 \sqrt{3}$

Breaking Down $\sqrt{12}$

To begin simplifying the expression $\sqrt{12} \cdot 4 \sqrt{3}$, our first task is to break down the square root of 12. This involves finding the prime factorization of 12, which will help us identify any perfect square factors. The prime factorization of 12 is $2 \times 2 \times 3$, which can be written as $2^2 \times 3$. Recognizing that $2^2$ is a perfect square (equal to 4), we can rewrite $\sqrt{12}$ as $\sqrt{2^2 \times 3}$. This step is crucial because it allows us to extract the square root of the perfect square, thereby simplifying the overall expression. Understanding how to identify and extract perfect square factors is a fundamental skill in simplifying square roots, and it forms the basis for many advanced mathematical manipulations. This process not only simplifies calculations but also reveals the underlying structure of the number, making it easier to work with in various mathematical contexts. By mastering this technique, students can confidently tackle more complex problems involving radicals and square roots.

Once we have the prime factorization of the number under the square root, the next step is to extract the square root of any perfect square factors. In our case, $\sqrt{12}$ can be rewritten as $\sqrt{2^2 \times 3}$. Using the property of square roots that $\sqrt{a \times b} = \sqrt{a} \times \sqrt{b}$, we can separate the square root of the perfect square factor from the rest. Thus, $\sqrt{2^2 \times 3}$ becomes $\sqrt{2^2} \times \sqrt{3}$. The square root of $2^2$ is simply 2, so we have $2 \sqrt{3}$. This transformation significantly simplifies the expression, making it easier to work with in subsequent steps. The ability to break down and simplify square roots is essential not only in algebra but also in various other branches of mathematics and science. It allows for more efficient calculations and a clearer understanding of mathematical relationships. This foundational skill is a key component of mathematical fluency and is crucial for success in higher-level math courses.

By rewriting $\sqrt{12}$ as $2 \sqrt{3}$, we have made significant progress in simplifying the original expression. This step demonstrates the power of prime factorization and the properties of square roots in reducing complex terms to their simplest forms. The process of identifying perfect square factors and extracting their square roots is a fundamental technique that is widely used in various mathematical contexts. It not only simplifies calculations but also provides a deeper understanding of the structure of numbers and their relationships. This skill is particularly valuable in algebra, where simplifying expressions is a crucial step in solving equations and inequalities. Furthermore, it is an essential tool in calculus, where the ability to manipulate and simplify expressions is necessary for differentiation and integration. By mastering this technique, students can develop a stronger foundation in mathematics and enhance their problem-solving abilities.

Combining the Terms

Now that we have simplified $\sqrt{12}$ to $2 \sqrt{3}$, we can substitute this back into the original expression. The expression $\sqrt{12} \cdot 4 \sqrt{3}$ now becomes $2 \sqrt{3} \cdot 4 \sqrt{3}$. This substitution is a critical step in the simplification process, as it replaces a more complex term with a simpler equivalent, making the overall expression easier to manage. Understanding how to make such substitutions is a key skill in algebra, allowing for the simplification of complex equations and the solution of problems that might otherwise seem intractable. This process not only reduces the complexity of the expression but also reveals the underlying structure and relationships, making it easier to perform further calculations and manipulations. The ability to confidently substitute simplified terms back into an expression is a hallmark of mathematical fluency and is essential for success in advanced mathematics.

With the expression rewritten as $2 \sqrt{3} \cdot 4 \sqrt{3}$, we can now apply the commutative and associative properties of multiplication to rearrange and group the terms. The commutative property allows us to change the order of multiplication without affecting the result (i.e., $a \cdot b = b \cdot a$), while the associative property allows us to change the grouping of factors without changing the result (i.e., $(a \cdot b) \cdot c = a \cdot (b \cdot c)$). Applying these properties, we can rewrite the expression as $(2 \cdot 4) \cdot (\sqrt{3} \cdot \sqrt{3})$. This rearrangement is a crucial step in simplifying the expression, as it groups the integer coefficients and the square root terms together, making it easier to perform the multiplication. Understanding and applying these properties is fundamental to algebraic manipulation and simplification, and it is a key skill for solving a wide range of mathematical problems. By mastering these techniques, students can confidently rearrange and simplify complex expressions, making them more manageable and easier to understand.

Grouping the coefficients and square roots together, we have $(2 \cdot 4) \cdot (\sqrt{3} \cdot \sqrt{3})$. Now, we can perform the multiplication within each group. First, $2 \cdot 4$ equals 8. Then, we need to consider the product of the square roots, $\sqrt{3} \cdot \sqrt{3}$. According to the properties of square roots, the product of a square root with itself is the original number (i.e., $\sqrt{a} \cdot \sqrt{a} = a$). Therefore, $\sqrt{3} \cdot \sqrt{3}$ equals 3. This simplification is a key step in reducing the expression to its simplest form. Understanding this property of square roots is essential for simplifying expressions and solving equations involving radicals. It allows us to eliminate square roots from expressions, making them easier to work with and understand. This skill is particularly useful in algebra and calculus, where manipulating and simplifying expressions is a fundamental part of problem-solving. By mastering this technique, students can confidently handle expressions involving square roots and radicals, enhancing their mathematical fluency and problem-solving abilities.
