Pertanyaan

Jika 2 log 3 = P dan 2 log 5 = Q
Maka 2 log 45 =

Answer 1

Materi Logaritma

^2 log 3 = P
^2 log 5 = Q

^2 log 45 = ^2 log (3 × 3 × 5)
= ^2 log 3 + ^2 log 3 + ^2 log 5
= P + P + Q = 2P + Q

Answer 2

2 log 45
= 2 log 3^2 x 5
= 2 log 3 ^2 + 2 log 5
= 2. 2 log 3 + 2 log 5
= 2. p + q
= 2p+q
