If you mean then:
1. There is no real value.
2. Talk about "under the root" is confusing and misleading. The correct term is "base", as in "The base of the log is e".
3. What is meant to be assumed by the multiplication symbol here:
I'm not talking about ln versus log or whatever. I'm talking about your incorrect use of the multiplication symbol and your incorrect use of the expression "under the root".
And as I have already said, the expression has no real value.
Are you attempting to find the non-real value? If so, then you should have said so in the first place. Otherwise, there's nothing more to be said.
