A number with a power is still a number - a fixed constant. The differential of a constant is always 0.
A degree of a differential equation is the highest power of highest order of a differential term of the equation. For example, 5(d^4 x/dx^4) - (dx/dx)^2 =7 Here 5(d^4x/dx^2) has the highest order and so the degree will be it's power which is 1.
Power is the change of work over the change of time, ΔW/Δt, or in differential form, dW/dt
