28. Jika A = 2log 2 log 4 log 256 + 2 √2 log 2
maka A = ...
a. 1
b. 2
c. 3
d. 5
e. 7
Jawaban : D
A = 2log 2 log 4 log 256 + 2 √2 log 2
A = 2log 2 log 4 log 44 + 2 2^1/2 log 2
A = 2log 2 log 4 . 4 log 4 + 2 . 1/(1/2) 2 log 2
A = 2log 2 log 4 + 2 . 2
A = 2log 2 log 22 + 4
A = 2log 2 .2 log 2 + 4
A = 2log 2 + 4
A = 1 + 4
A = 5
