Introduction

When dealing with mathematical expressions involving square roots, it's essential to understand the properties of radicals and how to simplify them. In this article, we will explore the process of simplifying the expression $10 \sqrt{5} \cdot 5 \sqrt{11}$ using the properties of radicals.

Understanding Radicals

A radical is a mathematical expression that represents a number that can be expressed as the product of a perfect square and another number. The radical symbol, denoted by $\sqrt{}$ , is used to represent the square root of a number. For example, $\sqrt{16}$ represents the number that, when multiplied by itself, gives 16.

Properties of Radicals

There are several properties of radicals that are essential to understand when simplifying expressions involving square roots. These properties include:

Product of Radicals: The product of two or more radicals is equal to the product of the numbers inside the radicals. For example, $\sqrt{a} \cdot \sqrt{b} = \sqrt{ab}$ .
Quotient of Radicals: The quotient of two or more radicals is equal to the quotient of the numbers inside the radicals. For example, $\frac{\sqrt{a}}{\sqrt{b}} = \sqrt{\frac{a}{b}}$ .
Power of a Radical: When a radical is raised to a power, the power can be brought down as an exponent. For example, $(\sqrt{a})^n = a^{\frac{n}{2}}$ .

Simplifying the Expression

To simplify the expression $10 \sqrt{5} \cdot 5 \sqrt{11}$ , we can use the properties of radicals. First, we can use the product of radicals property to combine the two radicals:

10 \sqrt{5} \cdot 5 \sqrt{11} = 10 \cdot 5 \cdot \sqrt{5} \cdot \sqrt{11}

Next, we can use the product of radicals property again to combine the two radicals:

10 \cdot 5 \cdot \sqrt{5} \cdot \sqrt{11} = 50 \cdot \sqrt{5 \cdot 11}

Now, we can simplify the expression inside the radical:

50 \cdot \sqrt{5 \cdot 11} = 50 \cdot \sqrt{55}

Final Answer

The final answer to the expression $10 \sqrt{5} \cdot 5 \sqrt{11}$ is $50 \sqrt{55}$ .

Conclusion

Simplifying expressions involving square roots requires a good understanding of the properties of radicals. By using the product of radicals property, we can combine two or more radicals and simplify the expression. In this article, we have explored the process of simplifying the expression $10 \sqrt{5} \cdot 5 \sqrt{11}$ using the properties of radicals.

Additional Examples

Here are a few additional examples of simplifying expressions involving square roots:

$\sqrt{16} \cdot \sqrt{9} = \sqrt{16 \cdot 9} = \sqrt{144} = 12$
$\frac{\sqrt{25}}{\sqrt{4}} = \sqrt{\frac{25}{4}} = \frac{5}{2}$
$(\sqrt{9})^3 = 9^{\frac{3}{2}} = 729$
