Usa a fórmula dos juros compostos:
M = c . (1+i)^t
4c = c . (1+0,08)^t
4 = (1,08)^t
4 = (108/100)^t
log 2² = log (108/100)^t
0,60 = t . (log 108 - log 100)
0,60 = t . (log 108 - 2)
0,60 = t . (log 2² . 3³ - 2)
0,60 = t . (log 2² + log 3³ - 2)
0,60 = t . (2 . log2 + 3.log3 - 2)
0,60 = t . (0,60 + 1,44 - 2)
0,60 = t . (0,04)
t = 15
