Question

²log18 - ½^log0,25 + ³log1/3³ + 2log1

Answer 1

= ²log18 - ²log0,25 + ³log(3⁻³) + 0
= ²log18 - ²log0,25 + (- 3)
= - 3 + ²㏒ [18/0,25]
= - 3 + ²㏒72

Seandainya bukan ²log18 tetapi ²log8, perhatikan
= ²log8 - ²log0,25 + ³log(3⁻³) + 0
= ²log2³ - ²log0,25 + (- 3)
= 3 + ²㏒ [2⁻²] + (- 3)
= 3 + (- 2) + (- 3)
= - 2
