Question

qual a taxa de juros compostos que faz uma aplicação de $500,00 se transformar num montante de $709,26 após 6 meses?

Answer 1

$M = C \;.\; (1+taxa)^{periodo}\\\\709,26=500.(1+taxa)^{6}\\\\(1+taxa)^{6}=\frac{709,26}{500}\\ \\(1+taxa)^{6} = 1,4185\\\\(1+taxa) = \sqrt[6]{1,4185}\\ \\1+taxa=1,0600\\\\taxa = 1,0600-1\\\\taxa = 0,06\\ou\\taxa = 0,06 \times 100 = 6 \%$
