Verified Answer :

\(= (0.3)(-9.2)(-8.1)(4.2)(-0.8) \\ = (-2.76)(-8.1)(4.2)(-0.8) \\ = (22.356)(4.2)(-0.8) \\ = (93.8952)(-0.8) \\ = -75.11616\)

So, yeah the product is Nagative.

the simplest way is to count the number of NEGATIVE SIGNS in the problem before doing any multiplying
If there are an ODD number of NEGATIVE TERMS the answer is NEGATIVE
if an EVEN NUMBER the answer is POSITIVE

In this problem there are 3 negative terms, so the answer is NEGATIVE
after knowing the sign, just multiply the numbers without worrying about the sign, you already know it
