If both \(7^3\) and \(5^2\) are factors of the number \(u × 10^5 × 9^4 × 13^9\), then what is the smallest possible value of 'u'?

A. 575
B. 857
C. 8050
D. 8575
E. 8600
Did you copy the question accurately? Could you please share a screenshot, a photo, or a link to this question in the Princeton review materials?

 
­Yes sir, I did!

I thought the answer should be \(7^3\) But it was not in the options. 

Then to get the answer I saw which of these numbers are divisible by 7 and only D was divisible by 7. 

Is this question wrong?­
­Yest it is. Could you please share a screenshot, a photo, or a link to this question in the Princeton review materials?

Should I change the 4th option with 343? ­
