Which product is negative? −2⋅(−7)⋅12⋅(4)
−6⋅(−7)⋅(−8)⋅0
−3⋅(−2)⋅(−4)⋅(−7)
4⋅(−9)⋅(−3)⋅(−1)

Answers

Answer:

4⋅(−9)⋅(−3)⋅(−1) product is negative,

Step-by-step 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,

The negative answer is the last one, 4⋅(−9)⋅(−3)⋅(−1)

positive times a negative = a negative

negative times a negative= a positive

b^-3=1/216 b=?

743.8 × 103=?
36 ÷ 10–3=?
What is (2.1 × 103) × (4 × 10–7)?

Answers


-- A negative exponent means the number is in the denominator.
    b⁻³  means  1/b³ .
   So  1/b³ = 1/216 .                      You can do it now.

-- If that number is " 10³ ", it means 1,000 .
   If that number is " 103 " and you can't remember
   how to do multiplication with a pencil, then you'll
   have to use your calculator.

-- Again ...  10⁻³  means  1/10³  or  1/1000 .
   So the problem is really  36 divided by  1/1000 .
   Be very careful.  That means  36 x 1000 .

-- To multiply powers that have the same base,
   you add the exponents.

   Example:    10⁴  times  10⁵  =  10⁹ .

   This question can be rearranged as      (2.1 x 4) x (10³ x 10⁻⁷)

                                                                 (10³)  times  (10⁻⁷)   is  10⁻⁴  .

you have to find the common denominator(number that all of the denominators are divisible into.
the common denominator is 24
convert all the fraction accordingly 
Kathleen has 9/24 smoothie
penny has 20/24 smoothie
megan has 15/24 smoothie
