A comment by MarkFL in a https://mathhelpboards.com/pre-algebra-algebra-2/how-many-times-do-i-have-increase-3-a-24655.html#post110181 includes this formula:
[MATH]n=\left\lceil\frac{\ln\left(\dfrac{50}{3}\right)}{\ln(1.03)}\right\rceil[/MATH]
On my browser, that formula displays in a strange way:

Is that a quirk of my browser, or do other people get the same unbalanced delimiters?
If I replace the ceiling delimiters by brackets then the problem goes away, like this:
\(\displaystyle n=\left[\frac{\ln\left(\dfrac{50}{3}\right)}{\ln(1.03)}\right]\)
An alternative solution (which looks much neater to me) is not to insist that the inner fraction should be in displaystyle:
\(\displaystyle n=\left\lceil\frac{\ln\left(\frac{50}{3}\right)}{\ln(1.03)}\right\rceil\)
