Pertanyaan

jika alog=2;alogp =3,dan a log u³=21, tentukan alog t³pu

1 Jawaban

  • alog t = 2, alog p = 3 dan alog u^3 = 21.
    alog (t^3.p.u )
    = alog t^3 + alog p +alog u
    = 3.alog t + alog p + alog u
    = 3.2 + 3 + 7
    = 6 +6 +7
    = 19
    catatan: alog u^3 = 21. ==» 3.alog u =21 ==» alog u = 21/3 ==» alog u = 7
