$91\cdot27-27\cdot41+42\cdot50+31\cdot50=\\\\27\cdot(91-41)+50\cdot(42+31)\\\\27\cdot 50+50\cdot 73=\\\\50\cdot(27+73)=50\cdot100=5000$

Answer 2

Ответ:

5000

Пошаговое объяснение:

Вынесем за скобки общий множитель:

91 * 27 - 27 * 41 + 42 * 50 + 31 * 50 =

(91 * 27 - 27 * 41) + (42 * 50 + 31 * 50) =

27 * (91 - 41) + 50 * (42 + 31) =

27 * 50 + 50 * 73 = 50 * (27 + 73) = 50 * 100 = 5000

Answer 3

Let's calculate the expression step by step:

1. 91 • 27 = 2,457
2. 27 • 41 = 1,107
3. 42 • 50 = 2,100
4. 31 • 50 = 1,550

Now, let's add the results together:

2,457 - 1,107 + 2,100 + 1,550

Now, subtract 1,107 from 2,457:

2,457 - 1,107 = 1,350

Now, add the remaining numbers:

1,350 + 2,100 + 1,550 = 4,000

So, the result of the expression 91 • 27 - 27 • 41 + 42 • 50 + 31 • 50 is 4,000.
