Materi Logaritma Jawab dengan penjelasan

40.
log p = a
log q = b

log (p^3 . q^5)
= log p^3 + log q^5
= 3 log p + 5 log q
= 3a + 5b ➡ opsi D

41.
log 2 = 0,301
log 3 = 0,477

log ³√225
= log (15)^2/3
= 2/3 log 15
= 2/3 log (30/2)
= 2/3 (log 30 - log 2)
= 2/3 (log 10 + log 3 - log 2)
= 2/3 (1 + 0,477 - 0,301)
= 2/3 × 1,176
= 0,784 ➡ opsi E
