Question

Lumayan buat nambah poin kalian. tolong dijawab beserta caranya
Diketahui 3log5= p dan 2log3=q maka nilai 2log10 adalah=…….

Answer 1

3'log 5 = p 2'log 3 = q 2'log 3 . 3'log 5 = 2'log 5 = qp 2'log 10 = 3'log 10 / 3'log 2 = 3'log (2 × 5) / 3'log 2 = (3'log 2 + 3'log 5) / 3'log 2 = 1 + (3'log 5 / 3'log 2) = 1 + 2'log 5 = 1 + qp

Answer 2

^2log10 = ^3log10/^3log2
= ^3log(2x5) / ^3log2
= (^3log2 + ^3log5) / ^3log2
= (1/q + p) / 1/q
= (1 + pq )/q / 1/q
= ( 1 + pq)
