【单选题】幂指函数y=[f（x）]g（x）在求导时，可运用对数法：在函数解析式两边求对数得lny=g（x）lnf（x），两边同时求导得 =g'（x）lnf（x）+g（x） ，于是y'=[f（x）] g（x） [g'（x）lnf（x）+g（x） ]，运用此方法可以探求得知 的一个单调递增区间为 [ ]

【简答题】简述钢屋盖结构屋面支撑的种类。
【简答题】我们把形如y＝f(x) φ(x) 的函数称为幂指函数，幂指函数在求导时，可以利用对数法：在函数解析式两边求对数得ln y＝φ(x)lnf(x)，两边求导得 ＝φ′(x)·ln f(x)＋φ(x)· ，于是y′＝f(x) φ(x) [φ′(x)·ln f(x)＋φ(x)· ]．运用此方法可以探求得y＝x 的单调递增区间是________．
