Simplify the expression. c^-6 d^4/ c^-1 d^14 a. c ^10 /d^10. b. c^10 d^10 c. c^2 d^2 d. d^-2/d^-2.

u what ?

step-by-step explanation:

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
