Answer 1

Olá boa noite, veja a resolução da questão:

$48|2\\\\24|2\\\\ 12|2\\\\ 6|2\\\\ 3|3\\\\ 1|1~~----\\\\ ~~~~~~~~\large\boxed{\boxed{\boxed{2^4~\cdot~3}}}}}\\\\\\\ log~48 = 2^4~\cdot~3\\\\log~48= log~2^4+log~3\\\\ log~48=4~log~2+log~3\\\\\ log~48 = 4~\cdot~0,30+0,48\\\\\ log~48 = 1,2+0,48\\\\\\\ \large\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{log~48= 1,68.}}}}}}}}}}}}}}}}$

Espero que te ajude. :-).
