Question

4) Calcule log 192 ( Dados: log 2 = 0,30 e log 3 = 0,47 ).

a) 2,27
b) 1,83
c) 3,15
d) 0,77
e) 2,93

Answer 1

Explicação passo-a-passo:

$\sf log~192=log~(2^6\cdot3)$

$\sf log~192=log~2^6+log~3$

$\sf log~192=6\cdot log~2+log~3$

$\sf log~192=6\cdot0,30+0,47$

$\sf log~192=1,80+0,47$

$\sf log~192=2,27$
