Which two methods, in order, will best serve to find g'(d) if g(d) = (3d)(-6d^2+5)^3?

1. Product then quotient
2. Product then power
3. chain then power
4. power then product

Personally, I'd either:

1. Use the product rule, which means first using the chain rule to differentiate (-6d^2+5)^3, or

2. Re-write as g(d) = (-162 d^5 + 135 d^3) and then use the chain rule.
