280 is the answer ///////////////////////////////////
The answer to your question is 20/9
1.0
As x -> 0 2x -> 0, SqRt(2x) -> 0 & 3 SqRt(2x) -> 0
Hence:
3 SqRt(2x) + 1 -> 1.0
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.
