extreme (e^{3.4x})/(x^3)

extreme

Minimum (\frac{15}{17}, 29.23859 \dots)

Solution steps

f^{'} (x) = \frac{e ^{3.4 x} ( 3.4 x - 3 )}{x ^{4}}

Find intervals:

Decreasing

: - \infty < x < 0,

Decreasing

: 0 < x < \frac{15}{17},

Increasing

: \frac{15}{17} < x < \infty

Plug

x = \frac{15}{17}

into

\frac{e ^{3.4 x}}{x ^{3}} : 29.23859 \dots

Minimum (\frac{15}{17}, 29.23859 \dots)
