Tentukan nilai dari
a) ⁵log 200 - ⁵log 8
b) ³log 27 + ³log 9
c) ²log 64 + ³log 27 + ⁵log 125
a) ⁵log 200 - ⁵log 8
b) ³log 27 + ³log 9
c) ²log 64 + ³log 27 + ⁵log 125
Penjelasan dengan langkah-langkah:
a). ⁵log 200 - ⁵log 8
= ⁵log (200 ÷ 8)
= ⁵log 25
= ⁵log 5²
= 2
b). ³log 27 + ³log 9
= ³log (27 × 9)
= ³log 243
= ³log 3⁵
= 5
c). ²log 64 + ³log 27 + ⁵log 125
= (²log 2⁶) + ³log 27 + ⁵log 125
= 6 + (³log 3³) + ⁵log 125
= 6 + 3 + (⁵log 5³)
= 6 + 3 + 3
= 9 + 3
= 12
