To find how many times more people visit the Great Wall of China compared to Times Square, we need to compare the two values:
- The number of people visiting Times Square: \( 17^4 \)
- The number of people visiting the Great Wall of China: \( 17^6 \)
Now, we'll find the ratio of the number of visitors to the Great Wall to the number of visitors to Times Square:
\[ \text{Ratio} = \frac{17^6}{17^4} \]
Using the properties of exponents, this simplifies to:
\[ \text{Ratio} = 17^{6-4} = 17^2 \]
Calculating \( 17^2 \):
\[ 17^2 = 289 \]
This means that on an average weekend, 289 times more people visit the Great Wall of China than Times Square.
Thus, the correct response is:
289 times more people visited the Great Wall.
