Question

Sederhanakan:
c) ² log 15 + ² log 14 - ² log 105=...
d) 3 ³ log 2 + 2 ³ log 3 - ³ log 24=...

Answer 1

C. 2log (15.14:105)
= 2log2
= 1

D. 3(3log2) + 2(3log3) - 3log24
= 3log8 + 3log9 - 3log24
= 3log (8.9:24)
= 3log3
= 1

Answer 2

² log (15*14/105)
=² log 2
=1

³ log 2³ + ³ log 3² - ³ log 24
= ³ log (8*9/24)
= ³ log 3
= 1
