What is the value of 6k^-4 if k = -1?
A. -24
B. 1
C. 6
D. 24

C, the answer is 6.

Step-by-step explanation:

If you substitute -1 into the variable "k", it would look like this equation, 6(-1), if you then raise -1 to the power of -4, you would then get the value 1. Thus, 6 * 1 equals 6. C would be the correct answer.

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
