log5 [ (3/5)(15^3/8) / (81/8)]
well at least the 8 goes away easy
log5 [ 3 *225 * 3 / 81 ]
log5 [ 225/9 ]
2 log 5 (15/3)
LOL !!!
2 log5 (5)
2 :)
LOG(base5)(3/5)+3log(base5)(15/2)-log(base5)(81/8)

Maybe there is an easier way, but that was fun !
sorry I don't understand
Log5(3/5)+3log5(15/2)-log5(81/8)
Solution
Log5(3/5)×log5(15^3/2^3)
=Log5(3/5×3375/8)
=Log5(2025/8)/log5(81/8)
=Log5(2025/81)
=Log5(25)
=Log5(5^2)
=Therefore Log5(3/5)+3log5(15/2)-log5(81/8)=2log5(5)
