Question

Calcule o valor do logaritmo Log2 (10.5.3)​

Answer 1

sendo:

log(2) = 0.30103

log(3) = 0.47712

log(5) = 0.69897

agora:

log2(10 * 5 * 3) = log2(2 * 3 * 5^2)

= (log(2) + log(3) + 2log(5))/log(2)

= (  0.30103 + 0.47712 + 2 * 0.69897 ) / 0.30103

= 7.22881440388

Answer 2

Resposta:

7,23

Explicação passo-a-passo:

log2 (10.5.3)​ = (log10 + log5 + log3)/log2 = (log10 + log10/2 + log3)/log2 =

(log10 + log10 - log2 + log3)/log2 = (1 + 1 - 0, 3010 + 0,4771)/0,3010 =

2,1761/0,3010 = 7,23
