+4 What does 3 to the -1.9 power approximate to? I cant figure out the scientific calculator. it doesn't have a y to the x power.
+70 It's about:
$${{\mathtt{3}}}^{-{\mathtt{1.9}}} = \left({\frac{{\mathtt{1}}}{{{\mathtt{3}}}^{{\mathtt{1.9}}}}}\right) = {\mathtt{0.124\: \!013\: \!686}}$$

$${{\mathtt{3}}}^{-{\mathtt{1.9}}} = \left({\frac{{\mathtt{1}}}{{{\mathtt{3}}}^{{\mathtt{1.9}}}}}\right) = {\mathtt{0.124\: \!013\: \!686}}$$
