extreme f(x)=x^2log_{2}(x)

extreme

Minimum (\frac{1}{e}, - \frac{1}{2 e} lo g_{2} (e))

Solution steps

f^{'} (x) = \frac{x + 2 x ln ( x )}{ln ( 2 )}

Find intervals:

Decreasing

: 0 < x < \frac{1}{e},

Increasing

: \frac{1}{e} < x < \infty

Plug

x = \frac{1}{e}

into

x^{2} lo g_{2} (x) : - \frac{1}{2 e} lo g_{2} (e)

Minimum (\frac{1}{e}, - \frac{1}{2 e} lo g_{2} (e))
