The square root of VA might be W for a quite different reason, if I got him right. Also, VA as we know him is a real entity, not an apparent one. :-)
P.S.: I thought you were referring to another kind of VA. Yes, your VA does equal W. Sorry!

As an electric engineer and knowing Valentin, I can only share your point :-)

In one of his famous S&SMC , Valentin asked to find a solution on the HP-71B to the equation:
Abs(Ln(x*x)-Ln(x^2)) > 4.012007 (BTW, I found a solution ...)
In the same way, is it possible to have square of VA significantly different from the product of VA by VA?

Let's take all this with humour... :-)

I've made a great mistake (please see my updated reply to Valentín). So one possible answer to the square root of VA is 45, NOT W, if my line of thought matches Valentín's.

I am sorry for having misled all of you from the solution. Again, my apologies!

This and the answer to the first problem might give a hint to both solutions, in case no one has figured them out yet.

Best regards,

Gerson.
