Question

How do I solve p=e squared/r when solving for r? ​

Answer 1

Answer:
`\displaystyle r = (e^2)/(p)`

===============================================

Work Shown:

`p = (e^2)/(r)\\\\pr = e^2\\\\r = (e^2)/(p)\\\\`

Step-by-step explanation:

In the second step, I multiplied both sides by r to move it to the left side. Then I divided both sides by p to isolate r.

In short, the r and p swap places.
