Question

heeeeeelp
sabendo que log 2=0,301,log 3=0477,log 5=0,698,log 7=0,845,log 11=1,041,log 13=1,114 calcule :
1-log 210 ?​

Answer 1

Resposta:

log 210

decompondo em fatores primos 210, fica:

2 . 3 . 5 . 7 = 210

log 210 = log (2 . 3 . 5 . 7) = log 2 + log 3 + log 5 + log 7 = 0,301 + 0,477 + 0,698 + 0,845 = 2,321
