Question

3086•0,5+8,3+4,5-3,5•(72-71,4)

Answer 1

1553.7 вроде так

$3086 \times 0.5 + 8.3 + 4.5 - 3.5 \times (72 - 71.4$

Answer 2

Let's solve the expression step-by-step:

1. 3086 • 0.5 = 1543 (multiplication of 3086 and 0.5)
2. 1543 + 8.3 = 1551.3 (addition of 1543 and 8.3)
3. 1551.3 + 4.5 = 1555.8 (addition of 1551.3 and 4.5)
4. 72 - 71.4 = 0.6 (subtraction of 71.4 from 72)
5. 3.5 • 0.6 = 2.1 (multiplication of 3.5 and 0.6)
6. 1555.8 - 2.1 = 1553.7 (subtraction of 2.1 from 1555.8)

So, the final result is 1553.7.
