EXPONENTIALIBUS AC LOGARITHMIS. 81 CAP. VI. beat = 2n, erit $\frac{1+x}{x} = 2^{\frac{1}{100}}$ & $l\frac{1+x}{x} = \frac{1}{100} l2 = 0,0030103$; hinc $\frac{1+x}{x} = \frac{10069555}{10000000}$; ergo $x = \frac{10000000}{69555} = 144$, circiter; sufficit ergo si numerus hominum quotannis parte sua $\frac{1}{144}$ augeatur. Quam ob causam maxime ridiculae sunt eorum incredulorum hominum objectiones, qui negant tam brevi temporis spatio ab uno homine universam terram incolis impleri potuisse. 111. Potissimum autem Logarithmorum usus requiritur ad ejusmodi aequationes resolvendas, in quibus quantitas incognita in Exponentem ingreditur. Sic, si ad hujusmodi perveniatur aequationem $a^x = b$, ex qua incognitae $x$ valorem erui oporteat, hoc non nisi per Logarithmos effici poterit. Cum enim fit $a^x = [TRUNCATED]
