What you have typed most closly corresponds to:

$\displaystyle 3-\left(-\frac{1}{18}\right)=3+\frac{1}{18}\approx 3.05556$

but I suspect that is not what you mean.

May be you mean

$\displaystyle x=3^{-\frac{1}{18}}=1/3^{\frac{1}{18}}$ ?

which should be evaluatable on your calculator

or:

$\displaystyle x=e^{-\frac{1}{18}\ln(3)$
