Answered by Damon
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)

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)
