I got X = 3.0597 also. I graphed ln(x) and x^.1 and then looked for the interesection which was (3.0597, 1.1183). Therefore, isn't 3.05 the answer?

the answer shld really be \( 3<x \le 3.0597262 \)

OpenStudy (swissgirl):
whooopppps it should really be \( 3<x<3.0597262 \)

OpenStudy (swissgirl):
since from 3 till that point ln(x) is less than x^.01 It is an interval
