Question 622548
<font face="Times New Roman" size="+2">


Use the definition of the logarithm function:



*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y = \log_b(x) \ \ \Rightarrow\ \ b^y = x]


For example (recalling that *[tex \LARGE \ln] means *[tex \LARGE \log_e]):


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 3 = \log_e(x) \ \ \Rightarrow\ \ e^3 = x]


Looks like the first one is true.  Have fun with the others.

*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
