Question

se log de 3= 0,5 calcule log de 900

Answer 1

log900=

log(9. 100)

log9 + log100

log3² + log10²

2(log3) + 2(log10) ==> log10=1

2(0,5) + 2(1)

1 + 2 = 3 ✓

Answer 2

Resposta:

$log(900) = \\ log(10 \times 10\times 3 \times3 ) = \\ log(10) + log(10) + log(3) + log(3) = \\ 1 + 1 + 0.5 + 0.5 = \\ 2 + 1 = \\ 3$
