Sederhanakan:
g) ² log 7 x ⁴ log 8 x ⁷ log 4=...
h) 1/2 log 3 x ⁹ log 8=...
i) a log b² x 1/b log c³ x c log a=...

Answer 1

²log 7 x ⁴log 8 x ⁷log 4
=> log 7/log 2 x log 2³/log 2² x log 2²/ log 7
=> log 7/log 2 x 3/2 x log 2/log 2 x 2 x log 2/log 7
=> 3

1/2 log 3 x ⁹log 8
=> 1/2 log 3 x log 2³/log 3²
=> 1/2 log 3 x 3/2  x log 2/ log 3
=> 3/4 log 2
