Question

Dados log 2 = a
log 3 = b
log 5 = c
calcule :
log 6 =
log 15 =
log 20 = ​

Answer 1

Resposta:

log 6 = a + b

log 15 = b + c

log 20 = 2a + c

Explicação passo-a-passo:

log 6 = log 2 x 3 = log 2 + log 3 = a + b

log 15 = log 3 x 5 = log 3 + log 5 = b + c

log 20 = log 2 x 2 x 5 = log 2 + log 2 + log 5 = 2a + c
