Question

Se log2=0,30 e log3=0,47 qual o log60?

Answer 1

$log2=0,30~~ e~~ log3=0,47$
$\large\boxed{log~60 = log ~^{3.2.10} }$

$log3+ log2+ log10 ^{10} = 0,47+0,30+ 1 = 1,77$

$\Large\boxed{Portanto , ~log~60 = 1,77}$

Answer 2

Estando todos os dados fornecidos na base 10, teremos:
log60 = log 2+ log 3+ log 10= 0,30+0,47+1= 1,77
