Question

Помогите выразить v3 не могу понять как P3\P4=(V4\V3)^k

Answer 1

Всё очень просто. Надо возвести в степень правую часть, потом дальше в общем виде умножать.
V3^k дальше уже легко найти.
Удачи!!!

Answer 2

Expressing V3 in Terms of P3 and P4

To express V3 in terms of P3 and P4 using the formula P3/P4 = (V4/V3)^k, we can rearrange the formula to solve for V3. The formula for expressing V3 in terms of P3 and P4 is:

V3 = V4 * (P4/P3)^k

This formula allows us to calculate V3 using the values of V4, P3, P4, and k.

Example Calculation

For example, if we have: - V4 = 10 - P3 = 2 - P4 = 5 - k = 3

We can calculate V3 using the formula: V3 = 10 * (5/2)^3

V3 = 10 * (2.5)^3

V3 = 10 * 15.625

V3 = 156.25

So, in this example, V3 would be 156.25.

Additional Information

The formula provided allows for the calculation of V3 based on the given values of V4, P3, P4, and k. This formula is useful for scenarios where the relationship between these variables needs to be determined or when one variable needs to be expressed in terms of the others.

I hope this helps! If you have further questions or need additional assistance, feel free to ask.
