Answer:
-37
Step-by-step explanation:
-16+-11=-27
-20+10=-10
-27+-10=-37
We need to simplify this number. We begin by evaluating the numbers inside the equation. We can simplify this to:
Now, we evaluate this one step further. Because a negative exponent makes the number 1 over what it was, we can make this problem:
This becomes:
So, 1/4k is the answer. This is the same as C, so C is the right answer.
