After a special medicine is introduced into a petri dish full of bacteria, the number of bacteria remaining in the dish decreases rapidly.
The relationship between the elapsed time ttt, in seconds, and the number of bacteria, B(t)B(t)B, left parenthesis, t, right parenthesis, in the petri dish is modeled by the following function:
B(t)=6400⋅(0.81)t4
every second there is a % addition to/removal of the total number of bacteria in the Petri dish.

Convert what is inside the parenthesis to sixths.

(3/6+2/6-1/6)^3+2/3x4/5

(4/6)^3+2/3x4/5

(2/3)^3+12/15

8/27+12/15

(8x12/27x15)

96/405

32/135

Don't know if that's right though
