Question

sabendo que log 2=0,30 e log 3=0,48,calcule:
a) log108
b) log 216

Answer 1

a) log 108 =2,0334

b) log 216 = 2,3344

Answer 2

Sabendo que log 2=0,30 e log 3=0,48,calcule:a) log108= log 2^2 + log3^3 ==>2log2+3log3
2(0,30)+3(0,48) ==> 0,60+1,44
==> 2,04

b) log 216 ==> log 2^3 + log3^3 ==>3log2+3log3
3(0,30)+3(0,48) ==> 0,90+1,44 
==> 2,34
