Question

-3,2:(-0,8) +(-1,4): 1/2 : (1-3/10 : (-1,8))

Answer 1

- 3,2 : (- 0,8) + (- 1,4) : 1/2 : (1 - 3/10 : (- 1,8)) = 1,6
1) 3/10 : (- 1,8) = 3/10 : (- 18/10) =  3/10 * (- 10/18) = - 3/18 = - 1/6  
2) 1 - (- 1/6) = 1 + 1/6 = 1 1/6
3) - 3,2 : (- 0,8) = 4
4) - 1,4 : 1/2 = - 14/10 * 2/1 = 28/10 = - 2 8/10 = - 2 4/5
5)  - 2 4/5 : 1 1/6 = - 14/5 : 7/6 = -14/5 * 6/7 = - 12/5 = - 2 2/5
6) 4 + (- 2 2/5) = 4 - 2 2/5 = 3 5/5 - 2 2/5 = 1 3/5 = 1,6

Answer 2

It seems like you're providing a series of mathematical operations with vectors and scalars. Let's break it down step by step:

1. Start with the vector (-3, 2): (-3, 2)

2. Subtract the vector (-0, 8) from it: (-3, 2) - (0, 8) = (-3, 2) - (0, 8) = (-3, 2) - (0, 8) = (-3, -6)

3. Next, divide this result by the scalar 1/2: (-3, -6) / (1/2) = (-3, -6) * 2 = (-6, -12)

4. Now, we have the vector (-6, -12), and we'll perform another division, this time by the scalar 1 - 3/10, which is 7/10: (-6, -12) / (7/10) = (-6, -12) * (10/7) = (-60/7, -120/7)

5. Finally, let's divide this result by the vector (-1, 8): (-60/7, -120/7) / (-1, 8) = (-60/7, -120/7) / (-1, 8)

The final result depends on how you want to interpret this division. If you want to perform element-wise division of the vectors, then it would look like this:

((-60/7) / (-1), (-120/7) / 8) = (60/7, -15/7)

So, the final result is (60/7, -15/7) when performing element-wise division.
