Apparently you have posted the inequality incorrectly.
is always far less than

Comment to the student, who proclaims that I have not answered the problem in the correct way....
The graph shows that ln(4x-11) (green line) does not exist for x less than 11/4=2.75.
But the question was not where the function ln(4x-11) is defined.
The question was what is the solution set for the inequality; the graph shows that ln(x^2)-16 (red curve) is ALWAYS less than ln(4x-11), so the inequality is always true, which is what my answer said.
