Resposta:
a)0,77
b)0,70
c)1,07
d)1,88
e)2,30
Explicação passo-a-passo:
log2 =0,30 log3 =0,47
log6 >> log2.3 >> log2 + log3 >> 0,30+0,47= 0,77
log5 >> log10/2 >> log10 - log2 >> 1-0,30 = 0,70
log12 >> log2².3 >> 2log2 + log3 >> 2.0,30 + 0,47 = 1,07
log81 >> log3⁴ >> 4log3 >> 4.0,47 = 1,88
log 200 >> log2.100 >> log2 + log100 = 2,30
