12a. Answer: d) x⁶ f'(x) + 6x⁵ f(x)
<u>Step-by-step explanation:</u>
Use the multiplication formula for derivatives:
y = a · b → y' = a'b + ab'
<u>y = x⁶ · f(x) </u>
a = x⁶ b = f(x)
a' = 6x⁵ b' = f'(x)
<u>y' = a'b + ab'</u>
y' = 6x⁵ f(x) + x⁶ f'(x)

12b. Answer: 
<u>Step-by-step explanation:</u>
Use the division formula for derivatives:
→ 
Note: You can also move the denominator to the top (it will have a negative exponent) and use the multiplication formula for derivatives.
I think it's cost price
I heard it before somewhere
Hope I've been any help to you
Answer:
D
