Question

Which product is negative?

−4⋅(−6)⋅(−3)⋅(−5)−4⋅(−6)⋅(−3)⋅(−5)

−3⋅5⋅(−6)⋅4−3⋅5⋅(−6)⋅4

−3⋅4⋅(−2)⋅(−7)−3⋅4⋅(−2)⋅(−7)

−7⋅(−3)⋅(−9)⋅0

Answer 1

Hello Please help!

Answer 2

Alright let's look at the first one.
\[\ −4⋅(−6)⋅(−3)⋅(−5)−4⋅(−6)⋅(−3)⋅(−5)\]
Will do it in a quick way so
\[\ 360−(4)(−6)(−3)(−5)\]
\[\ 360−(72)(−5)\]
\[\ 360−(−360)\] So your answer would be positive \(\ 720\)

Answer 3

Ok

Answer 4

For the third one \[\ −3⋅4⋅(−2)⋅(−7)−3⋅4⋅(−2)⋅(−7) \]
\[\ (24)(−7)−(3)(4)(−2)(−7)\]
\[\ 168−(12)(−2)(−7)\]
\[\ −168−168\]
For this one the answer is negative \(\ −336\)

Answer 5

The last one would be \( 0\)..

Answer 6

so is it the last one?
