Step 1 :\(\frac{\left(2^{3} \times 2^{4}\right)^{2}}{\left(2^{2} \times 4^{3}\right)}\)
Step 2 :\(= \frac{2^{(3+4) \cdot 2}}{2^{2} \times (2^2)^{3}}\)
Step 3 :\(= \frac{2^{14}}{2^{2} \times 2^{6}}\)
Step 4 :\(= \frac{2^{14}}{2^{(2+6)}}\)
Step 5 :\(= 2^{(14-8)}\)
Step 6 :\(= 2^{6}\)
Step 7 :\(\boxed{64}\)
