Question

GENTEEEEEMMMMM   É  PARA AMANHÃ  :


CALCULE  LOG 13√3 / 4  , a partir  dos valores  log 2 = 0,30 , log 3 = 0,48 e log 13 = 1,11 :

Answer 1

Olá, Jacque.

$\log{\frac{13\sqrt3}{4}}=\\\\=\log{13}+\log{\sqrt3}-\log4=\\\\=1,11+\log{3^{\frac12}}-\log2^2=\\\\=1,11+\frac12\log3-2\log2=\\\\=1,11+\frac12\cdot0,48-2\cdot0,30=\\\\=1,11+0,24-0,60=\\\\=\boxed{0,75}$
