Solve the equation using natural logs. 29e^t/25=1700

29e^t / 25   = 1700

(29/25) e^t  = 1700

e^t =  1700  ( 25/29)

Take the Ln of both sides

Ln e^t  = Ln [ 1700 * 25 / 29]      and we  can write

t * Ln e  = Ln [ 1700 * 25 / 29  ]               Ln e  = 1....so we  can disregard it

t = Ln  [ 1700  * 25  /29  ]  ≈  7.29
