Tolong yang nomor 3 ya dari a sampai h

2A) 9log 27 = log 27 / log 9
= log 3^3 / log 3^2
= 3.,log 3 / 2.log 3
' ' = 3/2
B) 4log (1/32) = log (1/32) / log 4
= log (1/2)^5 / log 2^2
= log (2^-1)5 / 2.log 2
= log 2^-5 / 2.log 2
= -5.log 2 / 2.log 2
= -5/2 = -2 1/2
C) 5log 5.akar 5 = 5log (5.5^1/2)
= 5log 5^3/2
= 3/2
d) log 10 = 1
e) 25log 625 = 25log (25)^2
= 2
f) 16log (1/64) = log (1/64) / log 16
= log (1/4)^3 / log 4^2
= log (4^-1)^3 / 2.log 4
= log 4^-3 / 2.log 4
= -3.log 4 / 2.log 4
= -3/2
g) 2log 8.akar 2 = 2log (2^3)(2^1/2)
= 2log 2^7/2
= 7/2
h) (2akar2)log 16 = log 2^4 / log (2.2^1/2)
= 4.log 2 / log 2^3/2
= 4.log 2 / 3/2.log 2
= 4 /(3/2)
= 8/3
