Introduction


Radical expressions are a fundamental concept in algebra, and simplifying them is a crucial skill for any math enthusiast. In this article, we will explore the process of simplifying radical expressions, with a focus on the given problem: 5x73xâ‹…15x2\frac{\sqrt{5 x^7}}{\sqrt{3 x}} \cdot \sqrt{15 x^2}. We will break down the solution into manageable steps, using the properties of radicals and exponents to simplify the expression.

Understanding Radical Expressions


Before we dive into the solution, let's take a moment to understand what radical expressions are. A radical expression is any expression that contains a square root or other root symbol. The most common radical expression is the square root, denoted by the symbol \sqrt{}. For example, 4\sqrt{4} is a radical expression because it contains a square root.

Properties of Radicals


Radicals have several properties that make them easier to work with. Here are a few key properties:

  • Product Property: aâ‹…b=ab\sqrt{a} \cdot \sqrt{b} = \sqrt{ab}
  • Quotient Property: ab=ab\frac{\sqrt{a}}{\sqrt{b}} = \sqrt{\frac{a}{b}}
  • Power Property: ab=ab2\sqrt{a^b} = a^{\frac{b}{2}}

Simplifying the Given Expression


Now that we have a good understanding of radical expressions and their properties, let's simplify the given expression: 5x73xâ‹…15x2\frac{\sqrt{5 x^7}}{\sqrt{3 x}} \cdot \sqrt{15 x^2}.

Step 1: Simplify the Square Roots


To simplify the expression, we can start by simplifying the square roots. We can rewrite the expression as:

5x73xâ‹…15x2=5â‹…x73â‹…xâ‹…15x2\frac{\sqrt{5 x^7}}{\sqrt{3 x}} \cdot \sqrt{15 x^2} = \frac{\sqrt{5} \cdot \sqrt{x^7}}{\sqrt{3} \cdot \sqrt{x}} \cdot \sqrt{15 x^2}

Step 2: Apply the Product Property


Next, we can apply the product property to simplify the expression further:

5â‹…x73â‹…xâ‹…15x2=5â‹…x723â‹…x12â‹…15x2\frac{\sqrt{5} \cdot \sqrt{x^7}}{\sqrt{3} \cdot \sqrt{x}} \cdot \sqrt{15 x^2} = \frac{\sqrt{5} \cdot x^{\frac{7}{2}}}{\sqrt{3} \cdot x^{\frac{1}{2}}} \cdot \sqrt{15 x^2}

Step 3: Apply the Quotient Property


Now, we can apply the quotient property to simplify the expression further:

5⋅x723⋅x12⋅15x2=53⋅x72−12⋅15x2\frac{\sqrt{5} \cdot x^{\frac{7}{2}}}{\sqrt{3} \cdot x^{\frac{1}{2}}} \cdot \sqrt{15 x^2} = \sqrt{\frac{5}{3}} \cdot x^{\frac{7}{2} - \frac{1}{2}} \cdot \sqrt{15 x^2}

Step 4: Simplify the Exponents


Next, we can simplify the exponents:

53⋅x72−12⋅15x2=53⋅x3⋅15x2\sqrt{\frac{5}{3}} \cdot x^{\frac{7}{2} - \frac{1}{2}} \cdot \sqrt{15 x^2} = \sqrt{\frac{5}{3}} \cdot x^3 \cdot \sqrt{15 x^2}

Step 5: Apply the Product Property Again


Finally, we can apply the product property again to simplify the expression further:

53â‹…x3â‹…15x2=53â‹…15â‹…x6\sqrt{\frac{5}{3}} \cdot x^3 \cdot \sqrt{15 x^2} = \sqrt{\frac{5}{3} \cdot 15 \cdot x^6}

Step 6: Simplify the Expression


Now, we can simplify the expression:

53â‹…15â‹…x6=753â‹…x6=25â‹…x6=5x3x3\sqrt{\frac{5}{3} \cdot 15 \cdot x^6} = \sqrt{\frac{75}{3} \cdot x^6} = \sqrt{25 \cdot x^6} = 5 x^3 \sqrt{x^3}

Conclusion


In conclusion, the simplified expression is 5x3x35 x^3 \sqrt{x^3}. This is the final answer to the given problem.

Final Answer


The final answer is: 5x3x3\boxed{5 x^3 \sqrt{x^3}}
