solve for r.
r=(14,309.61/10,000)^1/5
Just in case my symbols are off, I will explain. The ^ symbol is means there is an exponent. So in the problem above the fraction in the parathensis to the 1/5 power.
The fraction exponent is throwing me off big time.

Are you looking for the answer? Why don't you use a calculator? It's not very hard to do on a calculator. This is what I got. 1.07429996

the denominator in a fractional exponent calculates as a root
in other words, 4^1/2 =2
that is, 4 to the 1/2 power is the same as the square root of 4
27^1/3 is 3 (the cube root of 27 is 3)
27^2/3 is the square of the cube root of 27 (or 9)
calculators today generally will evaluate fractional exponents
the windows pseudo-calculator solves r above as:
1.074299 (with more or less significant figures)

a fractional exponent means that you need to find that number root of the primary number
for example
4^(1/2) = sqrt 4 = 2
81^(1/4) = fourth root of 81 = 3
so take the fifth root of 14309.61/10000 = fifth root of .1430961
don't have a calculator but there you go.

Any real number can be an exponent. To calculate this one, you will need a scientific calculator (Windows comes with one).
For the concept or a rational exponent, see the source.
