³log 7 = p dan ⁵log 3 = q
²¹log525
= ³log 525 : ³log21
= ³log 3.7.5.5 : ³log 3.7
=³log 3 + ³log 7 + 2 ³log 5 : (³log 3 + ³log 7)
= 1 + p + 2 : ⁵log 3 + 1 + p
= 1 + p + 2 : q + 1 + p

NB : dibagi itu maksudnya per
jadi hasilnya 1+p+2 per q+1+p
bisa lebih disederhanain, jadi 3+p per q+1+p

=3 log 525: 3log 21
=3log 5 +3 log 105: 3 log 3+3 log 7
=1/5log3+ 3log 5+3log 21:1+p
=1/q+1/5log 3+ 3log 3+ 3log 7:1+p
=1/q+1/q+1+p:1+p
= 2/q+1+p:1+p
=(2/q: p+1) +p+1:p+1
= (2/q*1/p+1) +1
= 2/qp+q +1 atw. =2+(qp+q)/qp+q.


lw gk salah.
