Answer:
4⋅(−9)⋅(−3)⋅(−1) product is negative,
Explanation:
Given : Numbers .
To find : Which product is negative.
Solution : We have given expression with positive sign and negative sign.
By the integer rule : When we multiplied the even number of negative it become positive .
Example: -a * - b = ab.
When we multiplied the odd number of negative it become negative .
Example: -a * - b* -c = - abc.
This expression have −6⋅(−7)⋅(−8)⋅0 have 3 negative sign but it has 0 so, this expression would be zero.
Then only this 4⋅(−9)⋅(−3)⋅(−1) expression have 3 negative sign
So, its product would be negative.
Therefore, 4⋅(−9)⋅(−3)⋅(−1) product is negative,
