Question

Diketahui 5log4=p dan 3log5=q
maka 3log80=........

Answer 1

3log80 = 5log80/5log3
= 5log5+5log4+5log4/5log3
= 1+2p/1/q
= q + 2pq/1

Answer 2

Dik
5log4 = p
4log5 = 1/p
3log5 = q
5log3 = 1/q

3 log 80 = 5 log 80 = 5log4 + 5log4 5log5 = p + p + 1
5 log 3 5log3. 1/q
= pq/q + pq/q + q/q
1/q
= 2pq + q
