(a^x) logb = z , (b^y) log a = ....
jika ada alogb= c maka bloga=1/c
berarti
(a^x) logb = z
blog(a^x) = 1/z (jika ada alogb^n maka = n . alogb)
x . bloga= 1/z
bloga= 1/z/x
bloga= 1/xz
alogb= xz
kemudian (b^y) log a = ....( misalkan kita ibaratkan jwbnnya adalah N)
b^y loga = N
alog(b^y) = 1/N
y. alogb= 1/N (nilai alogb kita sudah mengetahuinya yaitu alogb= xz)
y. xz= 1/N
xyz= 1/N
1/xyz = N
N= 1/xyz
Jadi jawabannya (D)
(b^y) log a = 1/xyz
