Using the Quotient Rule of Exponents, which states that \( a^m \div a^n = a^{m-n} \), we can apply this to the expression \( 2^6 \div 2^3 \).
Applying the rule:
\[ 2^6 \div 2^3 = 2^{6-3} = 2^3 \]
Therefore, the equivalent form of \( 2^6 \div 2^3 \) is \( 2^3 \), which can also be referred to as "2 cubed".
So the correct response is:
2 cubed
