To simplify the expression \(\frac{6^{-4}}{6^{-1}}\), you can use the properties of exponents. According to the division rule for exponents:
\[ \frac{a^m}{a^n} = a^{m-n} \]
Applying this rule to the given expression:
\[ \frac{6^{-4}}{6^{-1}} = 6^{-4 - (-1)} = 6^{-4 + 1} = 6^{-3} \]
So the equivalent expression is:
\[ 6^{-3} \]
Now, let's look at the multiple choice answers provided:
- \(6^{5}\)
- \(6^{-4}\)
- \(6^{-3}\)
- \(6^{4}\)
The correct answer is:
\(6^{-3}\)
