The problem is to simplify:

$(2^3)^4 \times (2^3)^{-5}$

Solution:

1. Simplify the exponents: Using the rule of exponents $(a^m)^n = a^{m \cdot n}$, we simplify each term: $(2^3)^4 = 2^{3 \cdot 4} = 2^{12}$ $(2^3)^{-5} = 2^{3 \cdot (-5)} = 2^{-15}$

2. Combine the terms: Using the rule of exponents
