Question 809659: I am currently working on evaluation exponential function I know how to plug in the numbers..but when I set up the problem, the answer is not what I am getting and I don't know how..can you break it down for me?
A(t)=621(1/2)^t/30=
A(50) = 621(1/2)^50/30= 195.6 rounded = 196
HOW?
I need a breakdown of how this is the answer...Please help me

A(50) = 621(1/2)^(50/30)= 195.6
50/30=5/3
A(50) = 621(1/2)^(5/3)= 195.6
(1/2)^5/3=0.3149802624737182911918026518195570876425628661753769
621*0.3149802624737182911918026518195570876425628661753769=
195.60274299617905883010944677994495142603153989490907
