文[1]和文[2]各有一道方程a~x=│log_ax│习题和例题,经过研究发现两题都是错的,并引发了一些思考,写出来供大家参考和继续研究.文[1]习题:若0a,且1a≠,则方程xa=logax解的个数为()A.1B.2C.3D.1或2解答图像法:01a时,有两个交点;1a时,有1个交点,选(D).文[2]例题:已知01a,
Both [1] and [2] have an equation a~x=|log_ax| and exercises and examples. After the study, it is found that both questions are wrong, and it has led to some reflections, written for your reference and continued research. 1] Exercises: If 0a, and 1a ≠, then the number of solutions of the equation xa = logax is () A.1B.2C.3D.1 or 2 solution image method: 01a, there are two intersections; 1a, there is 1 point of intersection, selection (D). Text [2] Example: Known 01a,
