$**Simplify the Expression Completely: $\frac{3^0}{q^{-9}}$**$

Introduction

In mathematics, simplifying expressions is a crucial skill that helps us solve problems efficiently and accurately. When dealing with exponents and fractions, it's essential to understand the rules and properties that govern their behavior. In this article, we will simplify the expression $\frac{3^0}{q^{-9}}$ using the properties of exponents and fractions.

Understanding Exponents

Exponents are a shorthand way of representing repeated multiplication. For example, $3^4$ means $3 \times 3 \times 3 \times 3$ . When dealing with exponents, we need to remember the following properties:

Product of Powers: When multiplying two powers with the same base, we add their exponents. For example, $a^m \times a^n = a^{m+n}$ .
Power of a Power: When raising a power to another power, we multiply their exponents. For example, $(a^m)^n = a^{m \times n}$ .
Zero Exponent: Any non-zero number raised to the power of zero is equal to 1. For example, $a^0 = 1$ .

Simplifying the Expression

Now that we have a good understanding of exponents, let's simplify the expression $\frac{3^0}{q^{-9}}$ . To do this, we need to apply the properties of exponents and fractions.

First, let's simplify the numerator. Since $3^0 = 1$ , we can rewrite the expression as:

\frac{1}{q^{-9}}

Next, let's simplify the denominator. Since $q^{-9}$ means $q$ raised to the power of $-9$ , we can rewrite it as:

\frac{1}{\frac{1}{q^9}}

Now, let's simplify the fraction. When dividing by a fraction, we can multiply by its reciprocal instead. So, we can rewrite the expression as:

1 \times q^9

Using the product of powers property, we can simplify the expression further:

q^9

Conclusion

In this article, we simplified the expression $\frac{3^0}{q^{-9}}$ using the properties of exponents and fractions. We started by simplifying the numerator and denominator separately, and then combined them to get the final result. By understanding the rules and properties of exponents and fractions, we can simplify complex expressions and solve problems efficiently and accurately.

Q&A

Q: What is the difference between a fraction and an exponent?

A: A fraction is a way of representing a part of a whole, while an exponent is a shorthand way of representing repeated multiplication. For example, $\frac{1}{2}$ represents a fraction, while $2^3$ represents an exponent.

Q: How do I simplify a fraction with an exponent in the denominator?

A: To simplify a fraction with an exponent in the denominator, you need to apply the properties of exponents and fractions. For example, $\frac{1}{2^{-3}}$ can be simplified as follows:

\frac{1}{2^{-3}} = 2^3 = 8

Q: What is the rule for simplifying a fraction with a negative exponent?

A: When simplifying a fraction with a negative exponent, you need to apply the rule that $a^{-n} = \frac{1}{a^n}$ . For example, $\frac{1}{2^{-3}}$ can be simplified as follows:

\frac{1}{2^{-3}} = 2^3 = 8

Q: How do I simplify a fraction with a variable in the exponent?

A: To simplify a fraction with a variable in the exponent, you need to apply the properties of exponents and fractions. For example, $\frac{1}{x^{-3}}$ can be simplified as follows:

\frac{1}{x^{-3}} = x^3

Q: What is the difference between a positive and negative exponent?

A: A positive exponent represents repeated multiplication, while a negative exponent represents repeated division. For example, $2^3 = 8$ represents repeated multiplication, while $2^{-3} = \frac{1}{2^3} = \frac{1}{8}$ represents repeated division.

Q: How do I simplify a fraction with a variable in the numerator and a variable in the exponent in the denominator?

A: To simplify a fraction with a variable in the numerator and a variable in the exponent in the denominator, you need to apply the properties of exponents and fractions. For example, $\frac{x}{x^{-3}}$ can be simplified as follows:

\frac{x}{x^{-3}} = x \times x^3 = x^4
