\(\boxed {n}\)\(=(\frac{1}{n})^n\) for all integers n > 0. What is the value of \(\boxed {3}\) ?

A. \(\frac{1}{27}\)

B. \(\frac{1}{3}\)

C. \(1\)

D. \(3\)

E. \(27\)



Given: \(\boxed {n}\)\(=(\frac{1}{n})^n\) for all integers n > 0.
Asked: What is the value of \(\boxed {3}\)

\(\boxed {3}=(\frac{1}{3})^3 = \frac{1}{27}\)

IMO A
