指数型函数一般表现为复合函数形式,在求解时要注意分析函数表达式的结构特征,用不同的方法进行处理.下面就处理的方法举例分析.一、观察法 The exponential function generally behaves in the form of a compound function. During the solution, it is necessary to analyze the structural features of the function expression and use different methods for processing. The following example illustrates the processing method. First, the observation method
