Simplify.

Rewrite the expression in the form
\[4^n\].

\[\dfrac{4^{9}}{4^5}=\]

Using the quotient rule for exponents ($a^m / a^n = a^{m-n}$), we can simplify the expression as follows:

\[\dfrac{4^{9}}{4^5} = 4^{9-5} = 4^4 = \boxed{256}.\]

Using the quotient rule for exponents ($a^m / a^n = a^{m-n}$), we can simplify the expression as follows:

\[\dfrac{4^{9}}{4^5} = 4^{9-5} = 4^4 = \boxed{256}.\]

Simplify.

Rewrite the expression in the form
\[4^n\].

\[\dfrac{4^{9}}{4^5}=\]

To simplify the expression \(\frac{4^9}{4^5}\) in the form \(4^n\), we can use the rule of exponents which states that when you divide two powers with the same base, you subtract the exponents.

So, we can rewrite the expression as:

\(\frac{4^9}{4^5} = 4^{9-5}\)

Simplifying further, we have:

\(\frac{4^9}{4^5} = 4^4\)

Therefore, the expression \(\frac{4^9}{4^5}\) is equivalent to \(4^4\).
