Question

dados log2 = 0.301, log3 = 0,477, log5 = 0,699 e log7 = 0,845, calcule log 1,5 e log 56

Answer 1

Assunto: logaritmos.

• dados:

 log(2) = 0.301

 log(3) = 0.477

 log(7) = 0.845

• calcule log(1.5)

 log(1.5) = log(3/2) = log(3) - log(2)

 log(1.5) = 0.477 - 0.301 = 0.176

• calcule log(56)

 log(56) = log(8*7) = log(2³) + log(7)

 log(56) = 3log(2) + log(7)

 log(56) = 3*0.301 + 0.845 = 1.748
