manakah nilai yang terbesar ? logaritma kelas X

C. log 3 atau log 2 soalnya mereka terbesar diantara lainnyya

Nilai dasar logaritma :

Log 2 = 0,301
Log 3 = 0,477
Log 5 = 0,699
Log 7 = 0,845


a log a = 1


5 log 30 = log 30/log 5
= (log 6 x 5)/log 5
= (log 6 + log 5)/log 5
= ((log 2 + 3) + log 5)/log 5
= (0,301 + 0,477 + 0,699) / 0,699

= 1,477/0,699 =2,1



• Log 90 = Log 10 x 3 x 3
= Log 10 + log 3 + log 3
= 1 + 0,477 + 0,477
= 1,954

• 2 Log 3 = Log 3/Log 2
= 0,477/0,301
= 1,584

Maka jawabannya adalah a
