Problem

Simplify (6x^4)/(2x^6)

The question is asking you to perform the algebraic operation of simplification on the given rational expression, which is a fraction that consists of two polynomials. Specifically, the question requires you to simplify a fraction where the numerator is '6' multiplied by the variable 'x' raised to the power of '4' (6x^4), and the denominator is '2' multiplied by the variable 'x' raised to the power of '6' (2x^6). Simplifying this expression involves reducing it to its simplest form using algebraic rules concerning exponents and division of like terms.

Solution:

Step 1: Simplify the Numerical Coefficients

  • Identify and divide out the common numerical factor from the numerator and denominator.

Step 1.1: Factor Out the Common Numerical Coefficient

  • Express 6x4 as 2(3x4) to reveal the common factor: 2(3x4)2x6.

Step 1.2: Eliminate the Common Numerical Factors

  • Remove the common numerical factor from the fraction.

    • Step 1.2.1: Factor out the 2 from 2x6: 2(3x4)2(x6).

    • Step 1.2.2: Cancel out the 2: 2(3x4)2x6.

    • Step 1.2.3: Present the simplified expression: 3x4x6.

Step 2: Simplify the Variable Factors

  • Cancel out the common variable factors from the numerator and denominator.

Step 2.1: Factor Out the Common Variable Factor

  • Write 3x4 as x43: x43x6.

Step 2.2: Eliminate the Common Variable Factors

  • Remove the common variable factor from the fraction.

    • Step 2.2.1: Factor out x4 from x6: x43x4x2.

    • Step 2.2.2: Cancel out x4: x43x4x2.

    • Step 2.2.3: Present the final simplified expression: 3x2.

Knowledge Notes:

To simplify a fraction involving algebraic expressions, follow these steps:

  1. Factorization: Break down both the numerator and the denominator into their prime factors, including numerical coefficients and variables.

  2. Cancel Common Factors: If the same factor appears in both the numerator and the denominator, you can cancel it out. This is based on the property that aa=1 for any non-zero a.

  3. Apply Exponent Rules: When variables have exponents and you're dividing them, subtract the exponents if the base is the same (according to the quotient rule: xm/xn=xmn).

  4. Rewrite the Expression: After canceling, rewrite the expression to reflect the simplified form.

  5. Check for Further Simplification: Ensure that no further common factors can be canceled. If there are, repeat the process until the expression is fully simplified.

In the given problem, the numerical coefficient 6 in the numerator and 2 in the denominator have a common factor of 2, which is canceled out. Similarly, the variable x with exponents is simplified by subtracting the exponents in the numerator and denominator, resulting in the final simplified expression.
