nilai dari gambar tersebut.. A. 7 B. 1 C. -1 D. -3 E. -7

diselesaikan pembilang dulu
√5log 1/27 × √^3 (9)log 125 + √^3.16log 256
= log 3^-3 / log 5^1/2 × log 5^3/log 3^2/3 + log 2^8/ log 2^4/3
= -3.log 3/(1/2).log 5 × 3.log 5/(2/3).log 3 + 8.log 2/ (4/3).log 2.
= (-3)/(1/2) × (3)/(2/3) + (8)/(4/3)
= (-6)×(9/2) + 24/4
= -27 + 6
= -21
Penyebut => 2log 56 - 2log 7
= 2log (56/7)
= 2log 8
= 2log 2^3
= 3
Jadi pembilang / penyebut
= -21/3
= -7
