Question

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

Answer 1

C, the answer is 6.

Explanation:

If you substitute -1 into the variable "k", it would look like this equation, 6(-1)
`6(-1)^(-4)`, 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.

Answer 2

Answer: 6

Explanation:

`6\left(-1\right)^(-4)`

`6\cdot (1)/(\left(-1\right)^4)`

`6\cdot \:1`

`6`
