Question 452086
<font face="Times New Roman" size="+2">


Use the definition of logarithms.


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


Presuming you are using the standard convention that an unspecified base means base 10, then *[tex \Large y\ =\ -3] and  *[tex \Large b\ =\ 10], so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ -3 = \log_{10}(x) \ \ \Rightarrow\ \ 10^{-3} = x]


You can do your own arithmetic.

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