kak tlong ya... bantu dong

a. ²log (24×3) - ²log 9
= ² log (72/9)
= ²log 8
= ² log 2³
= 3 ² log 2
= 3

b. ^1/25log 125
=^5^-2 log 5³
=-3/2 ^5 log 5
= -3/2

c. log 5+ log 4-log 2+ log 10
= log (5×4)-log 2+log 10
= log (20/2)+log 10
=log 10+ log 10
= 1+1= 2

d. (² log 5× ^5 log 6) - ² log 24
= ² log 6 - (² log ( 3×8))
= ² log 3×2 -² log 3 - ² log 8
= ² log 3+²log2-² log 3- ² log 2³
= 1 -3
= -2

e. Jika log 2= 4 maka log 80?
log 80
= log 8×10
= log 2³+ log 10
= 3×4+ 1
= 13

f. ² log 20- ² log 125+ ²log 50
= ² log (20/125) +² log 50
= ² log {(4/25)×50}
= ² log 8= ² log 2³ = 3

* maaf kalau salah yaaa
