Need help differentiating

i= v/r (1-e^-Rt/L)


How would i go about differentiating this formula to get di/dt? Would I use the product rule or another rule?

Are v and r just constants in this?

If so, you basically just need the rule that tells you how to how to differentiate ekxe^{kx} w.r.t.x when k is a constant.
