Introduction

When dealing with radicals, it's essential to understand the properties and rules that govern them. In this article, we will explore the concept of reducing radicals, focusing on the given expression 180\sqrt{180}. We will break down the process into manageable steps, making it easier to grasp and apply the concepts.

Understanding Radicals

A radical is a mathematical expression that involves a root, typically a square root, cube root, or higher-order root. The radical sign, denoted by \sqrt{}, indicates that the expression inside the sign is to be taken as the root of the number. For example, 16\sqrt{16} means the number that, when multiplied by itself, gives 16.

Breaking Down the Given Expression

The given expression is 180\sqrt{180}. To reduce this radical, we need to find the largest perfect square that divides 180. A perfect square is a number that can be expressed as the square of an integer. For instance, 16 is a perfect square because it can be expressed as 424^2.

Step 1: Factorize 180

To find the largest perfect square that divides 180, we need to factorize 180. We can start by breaking down 180 into its prime factors:

180=2×2×3×3×5180 = 2 \times 2 \times 3 \times 3 \times 5

Step 2: Identify the Perfect Square

From the prime factorization of 180, we can see that there are two pairs of 2 and two pairs of 3. We can group these pairs together to form perfect squares:

180=(2×2)×(3×3)×5180 = (2 \times 2) \times (3 \times 3) \times 5

180=4×9×5180 = 4 \times 9 \times 5

Step 3: Simplify the Radical

Now that we have identified the perfect squares, we can simplify the radical:

180=4×9×5\sqrt{180} = \sqrt{4 \times 9 \times 5}

180=4×9×5\sqrt{180} = \sqrt{4} \times \sqrt{9} \times \sqrt{5}

180=2×3×5\sqrt{180} = 2 \times 3 \times \sqrt{5}

180=65\sqrt{180} = 6\sqrt{5}

Conclusion

Reducing radicals involves breaking down the expression into its prime factors and identifying the perfect squares. By following the steps outlined in this article, we can simplify radicals and express them in a more manageable form. The process of reducing radicals is essential in mathematics, particularly in algebra and geometry.

Q&A

Q: What is the difference between a radical and a square root?

A: A radical is a mathematical expression that involves a root, typically a square root, cube root, or higher-order root. The radical sign, denoted by \sqrt{}, indicates that the expression inside the sign is to be taken as the root of the number. A square root, on the other hand, is a specific type of radical that involves the square root of a number.

Q: How do I know if a number is a perfect square?

A: A perfect square is a number that can be expressed as the square of an integer. For example, 16 is a perfect square because it can be expressed as 424^2. To determine if a number is a perfect square, you can try to find the square root of the number and see if it is an integer.

Q: What is the largest perfect square that divides 180?

A: To find the largest perfect square that divides 180, we need to factorize 180 and identify the perfect squares. From the prime factorization of 180, we can see that there are two pairs of 2 and two pairs of 3. We can group these pairs together to form perfect squares:

180=(2×2)×(3×3)×5180 = (2 \times 2) \times (3 \times 3) \times 5

180=4×9×5180 = 4 \times 9 \times 5

Q: How do I simplify a radical?

A: To simplify a radical, you need to factorize the expression and identify the perfect squares. Then, you can group the perfect squares together and take the square root of each group. Finally, you can multiply the square roots together to get the simplified radical.
