**Solve the equation by finding a general solution.**

a) \(\frac{d^3 y}{dx^3} - 3 \frac{d^2 y}{dx^2} + 3 \frac{dy}{dx} - y = 0\)

b) \(\frac{d^3 y}{dx^3} - 3 \frac{d^2 y}{dx^2} + \frac{dy}{dx} - 3y = 0\)

c) \(\frac{d^3 y}{dx^3} + 2 \frac{d^2 y}{dx^2} + 4 \frac{dy}{dx} = 0\)

d) \(\frac{d^4 y}{dx^4} + 81y = 0\)

e) \(\frac{d^5 y}{dx^5} - \frac{d^4 y}{dx^4} - 16 \frac{dy}{dx} + 16 = 0\)

f) \(\frac{d^4 y}{dx^4} + 2 \frac{d^2 y}{dx^2} + y = 0\)

g) \(\frac{d^6 y}{dx^6} + 8 \frac{d^4 y}{dx^4} + 16 \frac{d^2 y}{dx^2} y = 0\)
