Introduction

In this article, we will explore the concept of rewriting an expression as a quotient of two powers. This involves applying the rules of exponents to simplify the given expression. We will focus on the expression (345)2\left(\frac{3}{4^5}\right)^2 and rewrite it as a quotient of two powers.

Understanding the Expression

The given expression is (345)2\left(\frac{3}{4^5}\right)^2. To rewrite this expression as a quotient of two powers, we need to apply the rules of exponents. The expression can be broken down into two parts: the numerator and the denominator.

  • The numerator is 3, which is a constant.
  • The denominator is 454^5, which is a power of 4.

Applying the Rules of Exponents

To rewrite the expression as a quotient of two powers, we need to apply the following rules of exponents:

  • Power of a Power Rule: (am)n=amn(a^m)^n = a^{mn}
  • Quotient of Powers Rule: aman=am−n\frac{a^m}{a^n} = a^{m-n}

We can start by applying the Power of a Power Rule to the denominator:

45=(22)5=22â‹…5=2104^5 = (2^2)^5 = 2^{2 \cdot 5} = 2^{10}

Now, we can rewrite the original expression as:

(345)2=(3210)2\left(\frac{3}{4^5}\right)^2 = \left(\frac{3}{2^{10}}\right)^2

Simplifying the Expression

Next, we can apply the Power of a Power Rule to the entire expression:

(3210)2=32(210)2=9220\left(\frac{3}{2^{10}}\right)^2 = \frac{3^2}{(2^{10})^2} = \frac{9}{2^{20}}

Rewriting as a Quotient of Two Powers

Finally, we can rewrite the expression as a quotient of two powers:

9220=32220=3222â‹…10=3222â‹…10\frac{9}{2^{20}} = \frac{3^2}{2^{20}} = \frac{3^2}{2^{2 \cdot 10}} = \frac{3^2}{2^{2 \cdot 10}}

Conclusion

In this article, we have rewritten the expression (345)2\left(\frac{3}{4^5}\right)^2 as a quotient of two powers. We applied the rules of exponents, including the Power of a Power Rule and the Quotient of Powers Rule, to simplify the expression. The final result is 32220\frac{3^2}{2^{20}}.

Key Takeaways

  • The Power of a Power Rule states that (am)n=amn(a^m)^n = a^{mn}.
  • The Quotient of Powers Rule states that aman=am−n\frac{a^m}{a^n} = a^{m-n}.
  • To rewrite an expression as a quotient of two powers, we need to apply the rules of exponents.
