son4ous [18]

Answer:

(2). -1

Step-by-step explanation:

The given parameter can be represented as:

(-1)^{2m + 1}

See comment for correct question

Required

The end result

From the question, we understand that m is a natural number

This means that:

2m + 1 \to odd number

So:

(-1)^{2m + 1} = -1 --- i.e. -1 to the power of an odd number will give -1

<em>Hence; (2) is correct</em>
