Ini apa yah jawabannya mohon..

²log 64 – 3 ²log 8 + 4 ²log 1/16 + 1/4 ²log 256
= ²log 64 – ²log8³ + ²log 1/16^4 + ²log 256^1/4
= ²log 4³ – ²log (2³)³ + ²log (4²)^-4 +²log 4
= ²log 4³ – ²log 2^9 + ²log 4^-8 +²log 4
= ²log 4³×4^-8×4 / 2^9
= ²log 4^-4 / 2^9
= ²log (2²)^-4 /2^9
= ²log 2^-8/2^9
= ²log 2^1
= ²log 2 = 1

semoga membantu 🙂
