Hasil [tex] \frac{ {}^{9} log8 \times ^{16} log27 - ^{ \sqrt{5} } log25 }{^{3} log9 + ^{3} log \frac{1}{27} } [/tex] adalah A. 25/8 B. 23/8 C. 7/4 D. -7/4

jawab

misal 
 p = ⁹log 8 . ¹⁶log 27  - √5'log 25
p = ³^² log 2³. ²^⁴log 3³ - ⁵^(1/2)log 5²
p = (3/2) . (3/4) - 2/(1/2)
p = 9/8 - 4

 q = ³log 9 + ³log 1/27
 q = ³log 3
q = 1

p/q = (9/8  - 4) /1  = (9 - 32)/(8) = - 23/8
