(-1)×(-1)×(-1)×(2m+1) times where m is a natural number,is equal to?

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>
