Question

qual a taxa semestral equivalente a 5,6% ao mes?

Answer 1

$Taxa_{semestral} = (1+taxa_{mensal})^6-1\\\\ Taxa_{semestral} = (1+0,056)^6-1\\\\ Taxa_{semestral} = 1,056^6-1\\\\ Taxa_{semestral} \approx 1,386703-1\\\\ \boxed{Taxa_{semestral} \approx 0,386703\ (\ \approx\ 38,6703\%\ a.s.\ )}$
