Question 548234
{{{(e^(1.273*75-4.705) )(0.83293)}}}?
According to my calculator, {{{1.273*75-4.705=95.475-4.705=90.77}}}, so that's going to be a really large number.
{{{(e^(1.273*75-4.705) )(0.83293)=0.83293e^90.77}}}
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
{{{2.195425109*10^39}}}
If this was science, and that 75 was considered an exact number, I would give the answer with 4 significant digits as {{{2.195*10^39}}}.
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 {{{2.20*10^39}}}, 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.
