"This looks a bit sketchy to me!I Interesting, but the whole point of "basic operations" is incorrect!

I don't mind Exponents and Decimal point. I will also pass Concatenation and Faactorial as a "basis operation that we have in our arsenal". Could be debated... but let it be!

But, since when is Sqare Root a basic operator?!? I don't mind the concept of Root as a basic operator...but when you write Root(of something) you mean 2ndRoot(of something). We don't write "2" there, just because the Mathematicians said let it be like this! It is the same as you would say that Log, or Ln are basic operators, when it means that if you have Log is just short for Log with base 10 (comes down to 10 fingers that you have on your hands) and Ln with base "e"...

What would happen if somebody in history said: "oh we have 3 dimensions of space... lets write 3rdRoot just as Root. That makes sence right!?!!" ?

Same scenario if we had 8 fingers on hand. Then Log8() would be writen just as Log... and probably the whole number system would be in base 8.... again going to far.

So basicly a topic for next video (like History lessons):

Since when is 2ndRoot() a basic operator and why?

(can do also for Log and Ln if you like)"
