Problem

Divide (8x^8y^8)/(x^5y^5)

The given problem involves the division of two algebraic expressions, specifically two monomials. The task is to simplify the expression by dividing one monomial by another, where the monomials are composed of variables raised to certain powers. The process typically involves applying the laws of exponents, which govern how to handle multiplication and division when working with exponential terms. In this case, you would need to subtract the exponents of the like bases in the numerator from those in the denominator to simplify the expression.

Answer

Expert–verified

Solution:

Step 1

Eliminate the common $x$ terms from the numerator and denominator.

Step 1.1

Extract $x^5$ from $8x^8y^8$ to get $\frac{x^5(8x^3y^8)}{x^5y^5}$.

Step 1.2

Simplify by removing the common factors.

Step 1.2.1

Take $x^5$ out of $x^5y^5$ to form $\frac{x^5(8x^3y^8)}{x^5(y^5)}$.

Step 1.2.2

Eliminate the matching $x^5$ terms to obtain $\frac{\cancel{x^5}(8x^3y^8)}{\cancel{x^5}y^5}$.

Step 1.2.3

Reformulate the fraction as $\frac{8x^3y^8}{y^5}$.

Step 2

Remove the common $y$ terms from the numerator and denominator.

Step 2.1

Factor out $y^5$ from $8x^3y^8$ to get $\frac{y^5(8x^3y^3)}{y^5}$.

Step 2.2

Simplify by canceling out the common factors.

Step 2.2.1

Multiply by $1$ to maintain equality, resulting in $\frac{y^5(8x^3y^3)}{y^5 \cdot 1}$.

Step 2.2.2

Eliminate the matching $y^5$ terms to achieve $\frac{\cancel{y^5}(8x^3y^3)}{\cancel{y^5} \cdot 1}$.

Step 2.2.3

Reformulate the fraction as $\frac{8x^3y^3}{1}$.

Step 2.2.4

Divide $8x^3y^3$ by $1$ to finalize the result as $8x^3y^3$.

Knowledge Notes:

The problem involves simplifying a fraction where both the numerator and the denominator contain powers of variables. The process uses the following algebraic rules and concepts:

  1. Exponent Laws: When dividing like bases with exponents, subtract the exponents: $x^a / x^b = x^{a-b}$.

  2. Cancellation: When the same term appears in both the numerator and the denominator, it can be cancelled out.

  3. Multiplying by 1: Multiplying a term by 1 does not change its value. This is often used to show that cancelling terms is valid, as it's equivalent to multiplying by a form of 1 (e.g., $x^5/x^5 = 1$).

  4. Simplifying Fractions: A fraction is fully simplified when no further common factors exist between the numerator and the denominator.

  5. Final Division by 1: Dividing any term by 1 leaves the term unchanged.

The solution process involves applying these rules step by step to simplify the given algebraic fraction to its simplest form.
