Square Root Of 162 In Radical Form Explained

Quick Links :

The square root of a number is a fundamental concept in mathematics, and understanding its radical form is crucial for various mathematical operations. In this article, we will delve into the concept of square roots, explore the radical form of the square root of 162, and provide a comprehensive explanation of the underlying mathematics.

What is a Square Root?

A square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 16 is 4, because 4 multiplied by 4 equals 16. The square root symbol is represented by a radical sign (√), and it is used to denote the square root of a number.

Why is the Radical Form Important?

The radical form of a square root is essential in mathematics because it provides a way to simplify complex expressions and equations. The radical form allows us to express square roots in a more compact and elegant way, making it easier to perform mathematical operations.

The Square Root of 162 in Radical Form

To find the square root of 162 in radical form, we need to factorize 162 into its prime factors. The prime factorization of 162 is:

162 = 2 × 3 × 3 × 3 × 3

Using the prime factorization, we can rewrite the square root of 162 as:

√162 = √(2 × 3 × 3 × 3 × 3)

Now, we can simplify the expression by taking out the perfect squares:

√162 = √(2 × 3^4)

Since 3^4 is a perfect square, we can rewrite it as:

√162 = 3√2 × 3

Finally, we can simplify the expression to:

√162 = 3√(2 × 3)

The radical form of the square root of 162 is 3√(2 × 3) or 3√6.

How to Simplify Radical Expressions

Simplifying radical expressions involves finding the prime factorization of the radicand (the number under the radical sign) and then simplifying the expression. Here are the steps to simplify radical expressions:

1. Find the prime factorization of the radicand.
2. Identify the perfect squares in the prime factorization.
3. Take out the perfect squares from under the radical sign.
4. Simplify the expression by combining like terms.

Examples of Simplifying Radical Expressions

Here are some examples of simplifying radical expressions:

• √12 = √(2 × 2 × 3) = 2√3
• √48 = √(2 × 2 × 2 × 2 × 3) = 4√3
• √75 = √(3 × 5 × 5) = 5√3
