Question

Does anyone know this?

Answer 1

`I = \sqrt{(P)/(R)}`

Start by squaring both sides. This ensures that we can get rid of the square root, and this makes it easier for us to deal with.


`I^(2) = (P)/(R)`

Now, multiply both sides by R, to get rid of the fraction.

`I^(2)R = P`

Now, simply divide both sides by the square of I.

`R = (P)/(I^(2))`

Answer 2

A. start by multiplying both side by sqrt(R), then square both sides.
