On a scale that measures the intensity of a certain phenomenon, a reading of n+1 corresponds to an intensity that is 10 times the intensity corresponding to a reading of n. On that scale, the intensity corresponding to a reading of 8 is how many times as great as the intensity corresponding to a reading of 3?  Choose the correct choice from the following.
A) 5
B) 50
C) 10^5
D) 5^10
E) 8^10 - 3^10
For n=3, consider the intensity to be x.   For n+1 = 4 , we have [intensity*10 ]= 10x   For n+2 = 5 , we have [10x*10 ]= 100x   For n+3  10 *10=

100x   For n+3= 6 , we have [100x*10 ]= 1000x   For n+4  100 *10=

1000x   For n+4= 7 , we have [1000x*10 ]= 10000x   For n+5  1000 *10=

10000x   For n+5= 8 , we have [10000x*10 ]= 100000x   Now , for n  10000 *10=

<output>100_000</output>
100000x   Now , for n= 8 --&gt;100000x = 10^5 x   which is 10^5 times x, the original intensity at n=3   ANSWER:10^5
