P = k/V
when P=20, V=500, so
20 = k/500
k = 10000
then P = 10000/V
if V - 400,
P = 10000/400 = 25
don't forget the units
PROOF: 2/LOG A BASE 9 - 1/ LOG A BASE 5 = 3/ LOG A BASE 3
thanks but how did you get 1000 by dividing k by 500?
I had 20 = k/500
now multiply both sides by 500
20(500) = (k/500)(500
10000=k
the 500's canceled on the right side
thank you so much! i really appreciate it!
