$\"%28e%5E%281.273%2A75-4.705%29+%29%280.83293%29\"$ ?
\n" ); document.write( "According to my calculator, $\"1.273%2A75-4.705=95.475-4.705=90.77\"$ , so that's going to be a really large number.
\n" ); document.write( " $\"%28e%5E%281.273%2A75-4.705%29+%29%280.83293%29=0.83293e%5E90.77\"$
\n" ); document.write( "It cannot be simplified further, and there is no exact answer that will not involve the irrational number e.
\n" ); document.write( "An approximate answer, according to my calculator is
\n" ); document.write( " $\"2.195425109%2A10%5E39\"$
\n" ); document.write( "If this was science, and that 75 was considered an exact number, I would give the answer with 4 significant digits as $\"2.195%2A10%5E39\"$ .
\n" ); document.write( "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 $\"2.20%2A10%5E39\"$ , 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. \n" ); document.write( "
