Not really. You potentially have a ten digit number. How you calculate the value depends on your purpose.

You could try , and then find the square of that, but still, do you want to account for all ten digits?

If a handheld electronic calculator is not available, then use a table of common logarithms, and just accept less than ten significant figures.
