pakai cara dn penjelasan pliss!! misal 2 log 3 =a , 3 log 5=b. maka 6 log 40 adalah??

= 3^log 40/ 3^log 6
= 3^log 2.2.5.2/ 3^log 2.3
= 3^log 2 + 3^log 2 + 3^log 2 + 3^log 5/ 3^ log 2 + 3^ log 3
= 1/2^log 3 + 1/2^log 3 + 1/2^log 3 + 3^log 5/ 1/2^log 3 + 3^log 3
= 1/a+1/a+1/a + b / 1/a + 1 x a/a
= 3 + ab/ 1+ a
mohon maaf
