The most accurate statement that summarizes how differences in military technology between the Spaniards and the Aztec and Inca affected their battles is:
"While the Indigenous forces would number in the thousands at times when battling the Europeans, they were still no match for the military prowess of the Spaniards."
This highlights the significant impact of military technology and tactics, including the Spaniards' use of gunpowder weapons, steel armor, and horses, which ultimately gave them a considerable advantage over the larger but less technologically advanced Indigenous forces.
