I have been reading this Wiki page and whilst I've been able to work through most of the examples, one is eluding me.

How do I break this equation down?

I have tried 10^1/30

Thanks in advance.

put the 1/30 in brackets, if you're then typing it into a calculator or excel it should then work:

so excel: =10^(1/30)

or scientific calculator: 10^(1/30)

Second that. If using calculator, type 10 then the yx button for the 10^ then put the 1/30 in brackets.

Simplified:
1/30 = 0.03333*
10^ 0.0333* = 1.079775.

The maths is pretty easy, it's knowing which buttons to push on the calculator. It's the Y to the power of X button, usually near the square root button.

Also, the 1/30 as a power can be rearranged....

10 = 1.079775^30

I'll not mention that the 1/30th power is the 30th root then.

Very interesting, but as a non mathematician, I can't see the point of such vast numbers...!

Oh no not again!

I'd forgotten about that, brain going into self preservation mode I think as then I had to read about Knuth Notation and TREE(3), and have a lie down.
