To use the Quotient Rule of Exponents, recall that for any base \( a \) and exponents \( m \) and \( n \), the Quotient Rule states:
\[ \frac{a^m}{a^n} = a^{m-n} \]
In your case, you have:
\[ \frac{2^8}{2^4} \]
Applying the Quotient Rule:
\[ 2^8 \div 2^4 = 2^{8-4} = 2^4 \]
So, an equivalent form of \( 2^8 \div 2^4 \) is \( 2^4 \).
