Math Problem Statement

The expression \(\frac{x^3 \cdot \sqrt[3]{x^3} \cdot x^5}{x^{-1/3}}\) is written as a single exponential \(x^n\). What is the value of \(n\)?

Solution

The expression given is:

x3x33x5x1/3\frac{x^3 \cdot \sqrt[3]{x^3} \cdot x^5}{x^{-1/3}}

We need to simplify this into the form xnx^n and determine the value of nn.

Step-by-step solution:

  1. Cube Root of x3x^3: x33=x3/3=x1\sqrt[3]{x^3} = x^{3/3} = x^1

  2. Multiply the terms in the numerator: x3x1x5=x3+1+5=x9x^3 \cdot x^1 \cdot x^5 = x^{3+1+5} = x^9

  3. Simplify the denominator: x1/3x^{-1/3}

  4. Combine the numerator and denominator using the rule xaxb=xab\frac{x^a}{x^b} = x^{a-b}: x9x1/3=x9(1/3)=x9+1/3\frac{x^9}{x^{-1/3}} = x^{9 - (-1/3)} = x^{9 + 1/3}

  5. Final expression: x9+1/3=x28/3x^{9 + 1/3} = x^{28/3}

Thus, the value of nn is:

n=283n = \frac{28}{3}
