Question

Mohon bantuannya ttg log

Answer 1

³log√3 + 2.³log 1/3 + ³log 27
= ³log(3)^(1/2) + 2.³log(3)⁻¹ + ³log 3³
= 1/2. ³log 3 + 2(-1).³log 3 + 3.³log 3
= 1/2 . 1 + (-2).1 + 3(1)
= 1/2 - 2 + 3
= 1/2 + 1
= 3/2 [A]

Answer 2

³log √3 + 2 x ³log 1/3 + ³log 27
= ³log 3¹/² + ³log (3⁻¹)² + ³log 3³
= ³log 3¹/² x 3⁻² x 3³
= ³log 3¹/² ⁻²⁺³
= ³log 3³/²
= 3/2 x ³log 3
= 3/2
Jawaban yang benar adalah a. 3/2
