Which Choices are Equivalent to the Expression Below?

Understanding the Given Expression

The given expression is $6 \sqrt{3}$ . This expression can be broken down into two parts: a numerical coefficient of 6 and a square root term of $\sqrt{3}$ . To find equivalent expressions, we need to manipulate the given expression using the properties of radicals.

Properties of Radicals

Before we dive into the equivalent expressions, let's recall some key properties of radicals:

Product Property: $\sqrt{a} \cdot \sqrt{b} = \sqrt{ab}$
Power Property: $(\sqrt{a})^n = a^{\frac{n}{2}}$
Quotient Property: $\frac{\sqrt{a}}{\sqrt{b}} = \sqrt{\frac{a}{b}}$

Equivalent Expressions

Now, let's analyze each choice to determine if it is equivalent to the given expression $6 \sqrt{3}$ .

A. $\sqrt{18} \cdot \sqrt{6}$

Using the product property, we can rewrite this expression as $\sqrt{18 \cdot 6} = \sqrt{108}$ . However, this is not equivalent to the given expression $6 \sqrt{3}$ .

B. $\sqrt{3} \cdot \sqrt{6}$

Using the product property, we can rewrite this expression as $\sqrt{3 \cdot 6} = \sqrt{18}$ . However, this is not equivalent to the given expression $6 \sqrt{3}$ .

C. 108

This choice is a numerical value, not an expression involving radicals. Therefore, it is not equivalent to the given expression $6 \sqrt{3}$ .

D. $\sqrt{108}$

Using the product property, we can rewrite this expression as $\sqrt{36 \cdot 3} = 6 \sqrt{3}$ . This is equivalent to the given expression.

E. $\sqrt{54}$

Using the product property, we can rewrite this expression as $\sqrt{9 \cdot 6} = 3 \sqrt{6}$ . However, this is not equivalent to the given expression $6 \sqrt{3}$ .

F. $\sqrt{3} \cdot \sqrt{6}$

This is the same as choice B, and we have already determined that it is not equivalent to the given expression $6 \sqrt{3}$ .

Conclusion

Based on our analysis, the only choice that is equivalent to the expression $6 \sqrt{3}$ is:

D. $\sqrt{108}$

This is because $\sqrt{108}$ can be rewritten as $6 \sqrt{3}$ using the product property.

Radicals Q&A: Frequently Asked Questions and Answers

Understanding Radicals

Q: What is a radical?

A: A radical is a mathematical expression that involves a square root or other root of a number. It is denoted by a symbol called a radical sign, which looks like a checkmark (√).

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

A: A radical is a general term that refers to any root of a number, while a square root is a specific type of radical that involves the square root of a number.
