According to my calculator,
, so that's going to be a really large number.
It cannot be simplified further, and there is no exact answer that will not involve the irrational number e.
An approximate answer, according to my calculator is
If this was science, and that 75 was considered an exact number, I would give the answer with 4 significant digits as
If the 75 was the result of a measurement that was not precise enough to be able to report the result as 75.0, or 75.00, then I would report it as
, and I would argue that the precision reflected in that result is closer to the precision reflected in 75, than the precision in the 2-significant digit answer that uses only 2.2. After all, when I report results of replicate assays, I may have 99.7%, along with 100.2%, and I do not let anyone complain that they have different number of significant figures.
