Vm= [(831,77+ 86,18)*10^-7*290,0-83,18x10^-6/2]*5*60x1,2

It seems like there's a typo or some confusion with the symbols in the expression provided. I'll clarify and correct the expression based on what I think you intended:

Given the expression:
\[
V_m = \left[\left(831.77 + 86.18\right) \times 10^{-7} \times 290.0 - 83.18 \times 10^{-6}/2\right] \times 5 \times 60 \times 1.2
\]

Let's break this down:

1. **First part inside the brackets:**
   - \( 831.77 + 86.18 \) gives us the sum.
   - Multiply this sum by \( 10^{-7} \) and then by 290.0.
   - Subtract \( \frac{83.18 \times 10^{-6}}{2} \) from the result.

2. **Multiplication by** \( 5 \times 60 \times 1.2 \) after the brackets.

Let me compute this for you.The value of \( V_m \) is approximately **9.57**.
