tolong bantuin?makasih

[tex]\log(1500)=\log(2^2\times3\times5^3)[/tex]
[tex]\log(1500)=\log(2^2)+\log(3)+\log(5^3)[/tex]
[tex]\log(1500)=2\log(2)+\log(3)+3\log(5)[/tex]
[tex]\log(1500)=2p+q+3r[/tex]

log 1500 = log (2² 3 5^3)
log 1500 = log (2²) + log 3 +log (5^3)
log 1500 = 2 log (2) + log (3) + 3log 5
log 1500 = 2p + q + 3r
