    What is e^(pi)?

    What is pi^(e)?

    Can the above be done without a calculator?

    Do you remember when calculators did not exist? I do!
    We used tables of logarithms.
    [math]\log(e^{\pi}}= \pi \log(e)= 3.1416(0.4343)= 1.3644[/math].
    The you look up 0,3644 in the body of the table to see that 0.3644 is the logarithm of 2.3142. Multiplying that by 10, for the leading "1", [math]e^{\pi}= 23.142[/math].

    Similarly, [math]\log(\pi^e}= e \log(\pi)= 2.7183(0.4971)= 1.3514[/math]
    Look up 0,3514 in the body of the table to see that 0,3514 is the logarithm of 2.2459. Multiplying that by 10, for the leading "1", [math]\pi^e= 22.459[/math].
