Understanding the Problem

When simplifying complex expressions, it's essential to break them down into manageable parts. In this case, we're given the expression 2+x8x3+xx\frac{\frac{2+x}{8x}}{\frac{3+x}{x}}. Our goal is to simplify this expression to its most basic form.

Step 1: Simplify the Complex Fraction

To simplify the complex fraction, we need to divide the numerator by the denominator. This can be achieved by multiplying the numerator by the reciprocal of the denominator.

2+x8x3+xx=2+x8xâ‹…x3+x\frac{\frac{2+x}{8x}}{\frac{3+x}{x}} = \frac{2+x}{8x} \cdot \frac{x}{3+x}

Step 2: Multiply the Numerators and Denominators

Now, we multiply the numerators and denominators separately.

(2+x)â‹…x8xâ‹…(3+x)\frac{(2+x) \cdot x}{8x \cdot (3+x)}

Step 3: Simplify the Expression

We can simplify the expression by canceling out common factors in the numerator and denominator.

(2+x)â‹…x8xâ‹…(3+x)=(2+x)8(3+x)\frac{(2+x) \cdot x}{8x \cdot (3+x)} = \frac{(2+x)}{8(3+x)}

Step 4: Choose the Correct Simplified Form

Now that we have simplified the expression, we can compare it to the given options.

  • Option A: 2+x8(3+x)\frac{2+x}{8(3+x)}
  • Option B: 2+x8\frac{2+x}{8}
  • Option C: 2+x3+x\frac{2+x}{3+x}
  • Option D: 2+x8x2\frac{2+x}{8x^2}

Based on our simplified expression, the correct answer is:

A. 2+x8(3+x)\frac{2+x}{8(3+x)}

Conclusion

Simplifying complex expressions requires breaking them down into manageable parts and applying the rules of arithmetic operations. By following the steps outlined above, we can simplify the expression 2+x8x3+xx\frac{\frac{2+x}{8x}}{\frac{3+x}{x}} to its most basic form.
