A. ⁵log 300 - 2 ⁵log 10 + ⁵log 9
B. ⁶log 9 . ³log 216 + ⁶log 5
Penjelasan dengan langkah-langkah:
Logaritma
.
A). ⁵log(300) - 2. ⁵log(10) + ⁵log(9)
= ⁵log(300) - ⁵log(10²) + ⁵log(9)
= ⁵log(300) - ⁵log(100) + ⁵log(9)
= ⁵log(300/100) x 9
= ⁵log(3 x 9)
= ⁵log(27)
= ⁵log(3³)
= 3. ⁵log(3)
.
B). ⁶log(9) . ³log(216) + ⁶log(5)
= ⁶log(3²) . ³log(6³) + ⁶log(5)
= 2.⁶log(3) . 3. ³log(6) + ⁶log(5)
= (2 x 3)(⁶log(3) . ³log(6)) + ⁶log(5)
= 6 + ⁶log(5)
