2e^(3t) = 400

e^(3t) = 200

3t = ln 200

t = (ln 200)/3

I think this might be :

 

2e ^(3t)  = 400   divide both sides by 2

 

e^(3t)  = 200      take the Ln of both sides

 

Ln e^(3t) = Ln 200    and we can write

 

(3t) Ln e   = Ln 200         Ln e   = 1  so we can ignore this

 

3t  = Ln 200          divide both sides by 3

 

t   = Ln 200 / 3  ≈  1.766

 

 

cool cool cool
