Question

Como posso fazer: Considerando log 2: 0,3010 e log 3: 0,4771

a) log raiz de 108?

b) log de 3000?

c) log 200?

Answer 1

Ola Gaby

log(√108) = log(108)/2

108 = 2^2 * 3^3

log(108) = 2log(2) + 3log(3)

log(108) = 2*0.3010 + 3*0.4771 = 2.0333

log(= √108) = log(108)/2 = 2.0333/2 = 1.01665

log(3000) = log(3) + log(1000) = 3 + log(3)

log(200) = log(2) + log(100) = 2 + log(2)
