#13th root

[askyindreaming]

Der deutsche Psychologe Gert Mittring brauchte sechs Minuten um etwas im Kopf auszurechnen, wofür andere ohne Taschenrechner verloren sind.

Who is this man and how do I come across him finally?

Recently I have watched a game show called “Super Brain”

Super Brain 2016 - China vs Japan 

And I keep searching for the most difficult mental calculations accomplished in world record and finally this man appears.

Some people think there must be a way to simplify the calculation so that it could turn into a humanly possible one, but what I feel amazed is his talent to find the way and also the time and effort he paid to make it successful.

Definitely there is more when I search through 13th root of a large number, and finally appears the world record holder,  Alexis Lemaire

Here is some info about his record:
