Answer 1

^ di baca pangkat

=2log18 - 2log8√2 + 2log(1/27)- 2log(1/3)
= 2 log ( 18 . 27^(-1))
--------------
( 8√2 . 3^(-1))

= 2log ( 3^2. 2. 3^(-3)) ->2 dgn 2^3 dicoret
--------------
( 2^3. 2^(1/2). 3^(-1))

=2log (3^(-1))
----------- --->3^(-1) dicoret
2^(5/2). 3^(-1))

= 2log (2^(-5/2))
= (-5/2) 2log2
= -5/2 opsi A
