Jika 9^log 8 = a hitunglah 4^log 3

Jika 9^log 8 = a hitunglah 4^log 3

Jawab:

$^9 log {8} = a$

$^{3^2} log {2^3} = a$

$frac{3}{2} : ^3 log {2} = a$

$^3 log {2} = frac{2}{3}a$

$^4 log {3} = : ^{2^2} log {3}$

$= frac{1}{2} : ^2 log {3}$

$= frac{1}{2} times frac{1}{^3 log {2}}$

$= frac{1}{2} times frac{1}{frac{2a}{3} }$

$= frac{1}{2} times frac{3}{2a}$

$= frac{3}{4a}$
