²log√8 + ²log√2 - ²log16 =

²log√8 + ²log√2 – ²log16 =

²log√8 + ²log√2 – ²log16 =
= ²log√8 + ²log√2 – 4
= $^{2}log(2^{3})^{ frac{1}{2} } + ^{2}log(2^{1})^{ frac{1}{2} } - 4= \ ^{2}log2^{ frac{3}{2} } + ^{2}log2^{ frac{1}{2} } - 4 = \ frac{3}{2} + frac{1}{2} - frac{8}{2} = -2$

3/2 + 1/2 – 4 = -2 itu dah jawabannya
