limit as x approaches infinity of xln(x)

解

x \to \infty lim (x ln (x))

解

\infty

解答ステップ

x \to \infty lim (x ln (x))

x \to a lim [f (x) \cdot g (x)] = x \to a lim f (x) \cdot x \to a lim g (x)

不定形式の場合を除く

= x \to \infty lim (x) \cdot x \to \infty lim (ln (x))

x \to \infty lim (x) = \infty

x \to \infty lim (ln (x)) = \infty

= \infty \cdot \infty

無限大の特性を適用する:

\infty \infty = \infty

= \infty
