=1/log(base8)36 + 1/log(base9)36 + 1/log(base8)36
=1/{log36/log8} + 1/{log36/log9} + 1/{log36/log18}
=log8/log36 + log9/log36 + log18/log36
={log8+log9+log18} /log36
= {3log2+2log3+log2+2log3}/{2log2+2log3}
={l4log2+4log3}/{2log2+2log3}
=4{log2+log3}/2{log2+log3}
=4/2
=2
=1/{log36/log8} + 1/{log36/log9} + 1/{log36/log18}
