Log540 

= ^3log540 / ^3log10

= ^3log 5.108 / ^3log5.2

= ^ 3log5 + ^3log 27.4 / ^3log5 + ^3log2

= ^3log5 + ^3log 3^3 + ^3log 2^2 / ^3log5 + ^3log2

= b + 3 + 2(1/a)  /  b + (1/a)

= ((ab + 3a + 2) / a) / ((ab + 1) / a)

= ((ab + 3a + 2) / a) . (a / (ab +1))
<a-nya coret>

jadi (ab + 3a + 2) / (ab +1)


Semoga membantu ya^^
