Question

Si el log de 8=9031, halla:

Answer 1

log8 = 0,9031 

Hallar : log800 = log8*100 = log8 + log100 = log8 + 2 = 0,9031 + 2 = 2,9031
entonces : log800 =  2,9031

log8 = 3log2 = 0,9031
entonces : log2 = 0,9031 = 0,301033333....
                              3
log0,64 = log(64/100) = log64 - log100 = 2log8 - 2 = 2(0,9031) - 2 =  - 0.1938
entonces : log0,64 = - 0,1938 

log40 = log4*10 = log4 + log10 = 2log2 + 1 = 2(0,3010333...) + 1 = 1,60206666....
entonces : log40 = 1,602066666.....
