Question

01- QUAL A TAXA ANUAL EQUIVALENTE À TAXA DE 5% A.M, NO REGIME DE CAPITALIZAÇÃO COMPOSTA?

Answer 1

1+ia=(1+im)elevado a 12
1+ia=(1+0,05)elevado a 12
1+ia=(1,05)elevado a 12
1+ia=1,7959
ia=1,7959 - 1
ia=0,7959
ia=79,59%

Answer 2

$taxa_{anual} = (1+taxa_{mensal})^{periodo}-1\\\\ taxa_{anual} = (1+0,05)^{12}-1\\\\ taxa_{anual} = 1,05^{12}-1\\\\ taxa_{anual} \approx 1,795856-1\\\\ \boxed{taxa_{anual} \approx 0,795856\ (\ \approx 79,5856\%\ a.a.\ )}$
