How do you express the current in a discharging capacitor.

I know that I = dQ/dt,

Qd = Q0e^(-t/RC)

I = d/dt (Q0e^(-t/RC))

= (Q/RC)e^(-t/RC)

I am confused because taking the derivative of Q0e^(-t/RC)) I think should be

(-Q/RC)e^(-t/RC) because the derivative of (-t/RC) is (-1/RC)

Which solution is correct

Thanks in advance
