Question

(-7)*(-0,5)*(-3)*(-2)(-1,25)*5*(-8)*(-6)0,2*(-25)*(-5)*40,5*(-20)*(-4)*(-8)​

Answer 1

А что сделать? Вычислить наиболее рациональным способом? Если ДА, то ответ ниже.

1. (-7)·(-3)·(-2)÷(-2)=(-7)·(-3)=21

2. (-5)·(-8)÷4·5·(-6)=10·(-30=-300

3. 2·(-5)÷10·(-25)·4=(-1)·(-100)=100

4. 5·(-4)÷10·(-20)·(-8)=(-2)·160=-320

Answer 2

To calculate the given expression:

(-7) * (-0.5) * (-3) * (-2) * (-1.25) * 5 * (-8) * (-6) * 0.2 * (-25) * (-5) * 40.5 * (-20) * (-4) * (-8)

Let's break it down step by step:

First, we can simplify the multiplication of the negative numbers by removing the negative signs:

7 * 0.5 * 3 * 2 * 1.25 * 5 * 8 * 6 * 0.2 * 25 * 5 * 40.5 * 20 * 4 * 8

Next, we can multiply the numbers together:

7 * 0.5 * 3 * 2 * 1.25 * 5 * 8 * 6 * 0.2 * 25 * 5 * 40.5 * 20 * 4 * 8 = 2,548,800

Therefore, the value of the expression is 2,548,800.
