: can someone help me with this problem:
The amount of particulate matter left in solution during a filtering process is given by the equuation P(x) = 800(2)^-0.4n, where n is the number of filtering steps. Find the amounts left for n = 0 and n = 5. (Round to the nearest whole number.)
a. 800, 25

P%28x%29+=+800%282%29%5E%28-0.4n%29

P%280%29=800%282%29%5E%280%29
P%280%29=800

P%285%29=800%282%29%5E%28%28-0.4%2A5%29%29
P%285%29=800%282%29%5E%28-2%29
P%285%29=800%2F4=200
