Answer 1

this is the correct method if you don't understand then tell me I will do it again for you

Answer 2

=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
