^3log 81 - 3 . ²log (1/32) + 2 . ^5log (5√5)
= ^3log 3^4 - 3 . ²log 2^(-5) + 2 . ^5log 5^(3/2)
= 4 . ^3log 3 - 3 . (-5) . ²log 2 + 2 . (3/2) . ^5log 5
= 4 + 15 + 3
= 22

3log 81 -3. 2log 1/32 +2. 5log 5√5
= 3log 3^4 - 2log (2^-5)^3 +5log (5^3/2)^2
= 4.3log 3 - 2log 2^-15 +5log 5^(3/2.2)
= 4 - -15. 2log 2 + 3. 5log 5
= 4 + 15 +3
= 22
