Question

-2*(-50)*6*1211*(-4)*(-7)*25-0,2*0,8*(-5)*(-1,25)​

Answer 1

Ответ:

1) -2 * (-50)*6*12 = 7200 ( произведение отрицательных на произ-е положит. чисел)

2) 11*(-4)*(-7)*25 = 25*(-4) * (-7)*11 = (-100) * (-77) = 7700 (понял как да, коммутативный закон)

3) -0.2*0.8*(-5)*(-1.25) = (-0.2) * (-5) *(0.8)*(-1.25) = 1*(-1) = -1 ( Тут надеюсь понял(а))

Answer 2

Let's simplify the expression step by step:

1. -2 * (-50) * 6 * 1211 * (-4) * (-7) * 25: -2 * (-50) = 100 100 * 6 = 600 600 * 1211 = 726600 726600 * (-4) = -2906400 -2906400 * (-7) = 20344800 20344800 * 25 = 508620000

2. -0.2 * 0.8 * (-5) * (-1.25): -0.2 * 0.8 = -0.16 -0.16 * (-5) = 0.8 0.8 * (-1.25) = -1.0

Now, subtract the result from step 2 from the result in step 1:

508620000 - (-1.0) = 508620001.0

So, the final result is 508620001.0.
