jika 10log 3 = p 10log 2 = q berapakah log 180?

log 180 = log (3.3.2.10)
             = log3 + log3 + log2 + log10
             = p + p + q + 1
             = 2p + q + 1


note:
10log3 = log3
jika bilangan basis logaritma tidak ditulis berarti bilangan basis 10.

¹⁰㏒ → ㏒
㏒ 180 = ㏒ (9 x 2 x 10)
㏒ 180 = ㏒ 9 + ㏒ 2 + ㏒ 10
㏒ 180 = ㏒ 3² + q + 1
㏒ 180 = 2p + q + 1
