Question

42:6+(19+6):5-6-2(27-19) •4+ 18:3+ (8+27):5-1760 - (13+ 22 ) :5-6.4+25​

Answer 1

Ответ: 4; 28; 71,6

Пошаговое объяснение:

1.

42 ÷ 6 + (19 + 6) ÷ 5 - 6 - 2 = 7 + 25 ÷ 5 - 6 - 2 = 7 + 5 - 6 - 2 = 12 - 8 = 4

2.

(27 - 19) × 4 + 18 ÷ 3 + (8 + 27) ÷ 5 - 17 = 8 × 4 + 6 + 35 ÷ 5 - 17 = 32 + 6 + 7 - 17 = 38 - 10 = 28

3.

60 - (13 + 22) ÷ 5 - 6,4 + 25 = 60 - 35 ÷ 5 - 6,4 + 25 = 60 - 7 - 6,4 + 25 = 85 - 13,4 = 71,6

Answer 2

Let's break down this mathematical expression step by step:

1. Start with the innermost parentheses:

   • (19 + 6) = 25
   • (27 - 19) = 8
   • (8 + 27) = 35
   • (13 + 22) = 35

2. Now we can rewrite the expression with these values:

   42/6 + 25/5 - 6 - 2*8 • 4 + 18/3 + 35/5 - 1760 - 35/5 - 6.4 + 25

3. Perform the multiplications and divisions from left to right:

   • 7 + 5 - 6 - 16 • 4 + 6 + 7 - 1760 - 7 - 6.4 + 25

4. Now, perform the remaining operations from left to right:

   • 7 + 5 - 6 - 64 + 6 + 7 - 1760 - 7 - 6.4 + 25

5. Continue to simplify:

   • 12 - 64 + 6 + 7 - 1760 - 7 - 6.4 + 25

6. Combine like terms:

   • 1776.4 - 64 + 6 + 7 + 25

7. Perform the final addition and subtraction:

   • 1698.4

So, the final result of the expression is approximately -1698.4.
