The discharge voltage for the capacitor is given by:
VC (t) = Vo exp(-t/RC) for t > or = 0
Here, t exp(-t/RC)
t=1*RC 0.37
t=2*RC 0.14
t=3*RC 0.05
t=4*RC 0.02
t=5*RC 0.01
So that practically we say that after 5 time constant capacitor is fully charged/Discharged.

What is the meaning of exponential?

Exponential is a graph which vary in form of pow(e, t) this curve is drawn between frequency and time.

Actually there are two responses one is transient response and steady state response steady state response occurs after the output becomes constant so it is almost equal to transient response so the answer is 5*RC.
