Question

(3×(-2))×5(-9×4)×(-2,5)(13×(-5))×20​

Answer 1

Ответ:

1)=(-6)*5=-30

2)=(-36)*(-2,5)=90

3)=(-65)*20=-1300

Answer 2

To simplify the expression:

(3×(-2))×5(-9×4)×(-2,5)(13×(-5))×20

Let's break it down step by step:

Step 1: Evaluate the multiplication and division within parentheses first.

(3×(-2)) = -6 (9×4) = 36 (13×(-5)) = -65

Step 2: Substitute the values obtained in Step 1 back into the expression:

-6×5(-9×4)×(-2,5)(-65)×20

Step 3: Evaluate the remaining multiplication and division operations:

5×(-9×4) = 5×(-36) = -180 -2,5×(-65) = -2.5×(-65) = 162.5

Step 4: Substitute the new values obtained in Step 3 back into the expression:

-6×(-180)×162.5×20

Step 5: Evaluate the remaining multiplication:

-6×(-180) = 1080

Step 6: Substitute the value obtained in Step 5 back into the expression:

1080×162.5×20

Step 7: Evaluate the remaining multiplication:

1080×162.5×20 = 3,510,000

So, the simplified expression is 3,510,000.
