If you had 2 to the third power, and you wanted to "prove" the result

the answer is 8.

2 to the 1/4 power is 1.189.

How do you "write out" 2 to the 1/4 power, to verify that?

Do it the other way round:

1.189 * 1.189 * 1.189 * 1.189 ~= 2

But I didn't know the answer (1.189) to begin with (I randomly found
that answer on Google.)

In the example of 2 to the third power, I know that the thing that
must be multiplied by itself is a 2.

But with 2 to the one-fourth power, how can ascertain what the thing
to be multiplied by itself is?

I see now that I asked that question badly. Whoops. But this Wikipedia
entry answers the question that I actually meant to ask, which is, How
am I going to arrive at 1.189 in the first place? And part of the
answer is: make an inital guess!

2^1/4 is actually a shortcut for writing the fourth root of 2. An
esier example is 4^1/2 = the square root of 4 = 2.
