Find The Quotient:$\[ \frac{x^6 Y^9}{x^{11} Y^{11}} = \\]

When dealing with algebraic expressions, simplifying exponents is a crucial step in solving equations and manipulating expressions. In this article, we will focus on simplifying the given expression $\frac{x^6 y^9}{x^{11} y^{11}}$ using the rules of exponents.

Understanding Exponents

Exponents are a shorthand way of representing repeated multiplication of a number. For example, $x^3$ can be read as "x to the power of 3" and is equivalent to $x \times x \times x$. When we have a fraction with exponents, we can simplify it by applying the rules of exponents.

Rules of Exponents

There are several rules of exponents that we can use to simplify expressions. These rules include:

• Product of Powers Rule: When we multiply two powers with the same base, we add the exponents. For example, $x^2 \times x^3 = x^{2+3} = x^5$.
• Quotient of Powers Rule: When we divide two powers with the same base, we subtract the exponents. For example, $\frac{x^2}{x^3} = x^{2-3} = x^{-1}$.
• Power of a Power Rule: When we raise a power to another power, we multiply the exponents. For example, $(x^2)^3 = x^{2 \times 3} = x^6$.

Simplifying the Expression

Now that we have a good understanding of the rules of exponents, let's apply them to simplify the given expression $\frac{x^6 y^9}{x^{11} y^{11}}$.

Using the quotient of powers rule, we can subtract the exponents in the numerator and denominator:

$$\frac{x^6 y^9}{x^{11} y^{11}} = x^{6-11} y^{9-11}$$

Simplifying the exponents, we get:

$$x^{-5} y^{-2}$$

Interpreting the Result

So, what does the simplified expression $x^{-5} y^{-2}$ mean? When we have a negative exponent, it means that we are taking the reciprocal of the base raised to the positive exponent. For example, $x^{-5}$ is equivalent to $\frac{1}{x^5}$.

Therefore, the simplified expression $x^{-5} y^{-2}$ can be rewritten as:

$$\frac{1}{x^5} \times \frac{1}{y^2}$$

Conclusion

In this article, we have learned how to simplify the expression $\frac{x^6 y^9}{x^{11} y^{11}}$ using the rules of exponents. By applying the quotient of powers rule, we were able to simplify the expression to $x^{-5} y^{-2}$. We also learned how to interpret the result, including the concept of negative exponents and the reciprocal of a base raised to a positive exponent.

Common Mistakes to Avoid

When simplifying expressions with exponents, there are several common mistakes to avoid. These include:

• Forgetting to apply the quotient of powers rule: When dividing two powers with the same base, we must subtract the exponents.
• Not simplifying the exponents: We must simplify the exponents in the numerator and denominator before applying the quotient of powers rule.
• Not interpreting the result correctly: We must understand the concept of negative exponents and the reciprocal of a base raised to a positive exponent.

Practice Problems

To practice simplifying expressions with exponents, try the following problems:

• $\frac{x^3 y^4}{x^5 y^6}$
• $\frac{x^2 y^3}{x^4 y^5}$
• $\frac{x^6 y^9}{x^{10} y^{12}}$

Real-World Applications

Simplifying expressions with exponents has many real-world applications. For example:

• Physics: When solving problems involving motion, we often need to simplify expressions with exponents to find the velocity or acceleration of an object.
• Engineering: When designing systems, we often need to simplify expressions with exponents to find the stress or strain on a material.
• Computer Science: When writing algorithms, we often need to simplify expressions with exponents to find the time or space complexity of a program.
