(log5√5+log√3+log45):log 15

[ log (5√5 . √3 . 45) ] : log 15
= log 15 : log 15
= 1

langsung cara ya

= log (5√5 × √3 × 45 )  / log 15
= log (15√5 × 45) / log 15
= log 225√5 /log 15
= log 15² × 15 pangkat 1/2 / log 15
= log 15 pangkat 5/2 - 1
= log 15 pangkat 3/2
= 3/2 log 15

klo gak salah jawabannya "D"
