Introduction

When dealing with fractions that contain exponents, it can be challenging to simplify them. However, with a clear understanding of the rules governing exponents, you can easily simplify fractions like $\frac{2^2}{2^5}$. In this article, we will delve into the world of exponents and explore the steps involved in simplifying fractions with exponents.

Understanding Exponents

---

Exponents are a shorthand way of representing repeated multiplication. For example, $2^3$ can be read as "2 to the power of 3" or "2 cubed." It is equivalent to $2 \times 2 \times 2$. Exponents can be positive or negative, and they can also be fractional.

Simplifying Exponents in Fractions

---

To simplify a fraction with exponents, we need to apply the rules of exponents. The first rule states that when we divide two powers with the same base, we subtract the exponents. This rule is represented by the equation $\frac{a^m}{a^n} = a^{m-n}$.

Applying the Rule to the Given Fraction

---

Now that we have a clear understanding of the rules governing exponents, let's apply them to the given fraction $\frac{2^2}{2^5}$. Using the rule $\frac{a^m}{a^n} = a^{m-n}$, we can rewrite the fraction as $2^{2-5}$.

Evaluating the Exponent

---

The next step is to evaluate the exponent $2-5$. When we subtract 5 from 2, we get $-3$. Therefore, the fraction $\frac{2^2}{2^5}$ can be simplified to $2^{-3}$.

Understanding Negative Exponents

---

A negative exponent is a fraction with a negative exponent. For example, $2^{-3}$ can be read as "2 to the power of negative 3" or "1 over 2 cubed." It is equivalent to $\frac{1}{2^3}$.

Simplifying Negative Exponents

---

To simplify a negative exponent, we can rewrite it as a fraction with a positive exponent. For example, $2^{-3}$ can be rewritten as $\frac{1}{2^3}$. This is equivalent to $\frac{1}{8}$.

Conclusion

---

In conclusion, simplifying fractions with exponents requires a clear understanding of the rules governing exponents. By applying the rule $\frac{a^m}{a^n} = a^{m-n}$, we can simplify fractions like $\frac{2^2}{2^5}$. We can also rewrite negative exponents as fractions with positive exponents. With practice and patience, you can become proficient in simplifying fractions with exponents.
