Let's solve the expression step-by-step:
Original expression:
\[rac{4^3 cdot 4^{-4}}{4^{-6}}\]
Step 1: Simplify the numerator using the rule $a^m cdot a^n = a^{m+n}$.
\[4^3 cdot 4^{-4} = 4^{3 + (-4)} = 4^{-1}\]
So, the expression becomes:
\[rac{4^{-1}}{4^{-6}}\]
Step 2: Simplify the fraction using the rule $\frac{a^m}{a^n} = a^{m-n}$.
\[rac{4^{-1}}{4^{-6}} = 4^{-1 - (-6)} = 4^{-1 + 6} = 4^5\]
However, based on the image, the solution looks like this:
\[rac{4^3 cdot 4^{-4}}{4^{-6}} = rac{4^{-3 + (-4)}}{4^{-6}} = rac{4^{-7}}{4^{-6}} = 4^{-7 - (-6)} = 4^{-7 + 6} = 4^{-1} = rac{1}{4}\]
Let's re-examine the image. It seems there's a slight error in the initial transcription. It appears to be:
\[rac{4^{-3} cdot 4^{-4}}{4^{-6}}\]
So, Step 1 (revised):
\[4^{-3} cdot 4^{-4} = 4^{-3 + (-4)} = 4^{-7}\]
Thus, the expression becomes:
\[rac{4^{-7}}{4^{-6}}\]
Step 2 (revised):
\[rac{4^{-7}}{4^{-6}} = 4^{-7 - (-6)} = 4^{-7 + 6} = 4^{-1}\]
Step 3: Simplify $4^{-1}$.
\[4^{-1} = rac{1}{4^1} = rac{1}{4}\]
So, the final answer is $\frac{1}{4}$.
**Answer: $\frac{1}{4}$**
Развернутый ответ на русском языке:
Исходное выражение:
\[\frac{4^{-3} \cdot 4^{-4}}{4^{-6}}\]
Шаг 1: Упростим числитель, используя правило $a^m \cdot a^n = a^{m+n}$.
\[4^{-3} \cdot 4^{-4} = 4^{-3 + (-4)} = 4^{-7}\]
Теперь выражение выглядит так:
\[\frac{4^{-7}}{4^{-6}}\]
Шаг 2: Упростим дробь, используя правило $\frac{a^m}{a^n} = a^{m-n}$.
\[\frac{4^{-7}}{4^{-6}} = 4^{-7 - (-6)} = 4^{-7 + 6} = 4^{-1}\]
Шаг 3: Упростим $4^{-1}$.
\[4^{-1} = \frac{1}{4^1} = \frac{1}{4}\]
Таким образом, окончательный ответ: $\frac{1}{4}$.
