pls help answer all thanks

What is the most appropriate differentiation rule to use in order to determine the derivative of the given function? Write the letter of your answer before the number. A. Power Rule C. Chain Rule B. Product Rule D. Quotient Rule 1. f(x) = (7x2 + 8)'(3x2 - 5x + 6) 6. f(x) = 2x" 2. f(x) = 2x5-7x4+34x2+235 X 7. f(x) = x-2 3. f(x) = 527x 8. f(x) = 2x - x2 +x3 4. f(x) = (2x2 - 9)5 9. f(x) = 2x(3x-9) (2x-5) (x-3)x 5. f(x) = (3x2-4)4x 10. f(x) = tan x+sin x x-9 (cosx) (x2) Determine the 3" derivative of the given function f(x) = (3x' - 5x + 6)4
