Understanding the Problem

When simplifying an expression involving exponents, it's essential to apply the rules of exponentiation correctly. In this case, we're given the expression $$\frac{x^{-6}}{y3}$$, and we need to simplify it.

Applying the Quotient Rule for Exponents

To simplify the expression, we can use the quotient rule for exponents, which states that when dividing two powers with the same base, we subtract the exponents. However, in this case, the bases are different, so we need to use a different approach.

Using the Rule for a Negative Exponent

When we have a negative exponent in the numerator, we can rewrite it as a positive exponent in the denominator by flipping the fraction. This means that $$x^{-6}$$ can be rewritten as $$\frac{1}{x^6}$$.

Simplifying the Expression

Now that we have rewritten the negative exponent, we can simplify the expression by dividing the numerator by the denominator. This gives us:

\frac{\frac{1}{x^6}}{y^3}

Applying the Quotient Rule for Fractions

To simplify the expression further, we can use the quotient rule for fractions, which states that when dividing two fractions, we multiply the first fraction by the reciprocal of the second fraction. This means that:

\frac{\frac{1}{x^6}}{y^3} = \frac{1}{x^6} \cdot \frac{1}{y^3}

Simplifying the Expression

Now that we have multiplied the fractions, we can simplify the expression by combining the exponents. This gives us:

\frac{1}{x^6} \cdot \frac{1}{y^3} = \frac{1}{x^6 y^3}

Conclusion

Therefore, the simplified expression is $$\frac{1}{x^6 y^3}$$.

Comparison with the Options

Let's compare our simplified expression with the options given:

Option A: $$\frac{1}{x^6 y^3}$$
Option B: $$\frac{y^3}{x6}$$
Option C: $$\frac{y^3}{x{-6}}$$
Option D: $$-x^6 y^3$$

Our simplified expression matches option A.

Final Answer

The final answer is option A: $$\frac{1}{x^6 y^3}$$.
