    my 3rd term is supposed to be sqrt 2. How else should i write it? all i can think of is 2 to the power of a half

    yes, first step, \(\log_2 (1/ 6\sqrt2)= \log_2 1- \log_2(6\sqrt 2)\) i think you are clear on this step. now for \(\log_2(6\sqrt2)\) use \(\log ab=\log a+\log b\)

    log 2(6) + log 2(2^1/2)

    correct, so far you have, \(\log_21-(\log_26+\log_22^{1/2})\) now take the term, \(\log_2 2^{1/2}=...?\)

    Also, log of 1 in any base = 0 because a^0 =1

    correct, so are you clear till here : \(0-(\log 6+1/2)\) now how can you write 6 as ?

    yes, but its still needs to simplify

    oh you can write 6 as -(log2(3) + log2(2) +1/2) -(log2(3) + 3/2)

    do one thing, right click on that tick, select 'Show Math As' and then "Tex Commands" and then copy that code. :)

    or copy this : `\huge \color{red}{\checkmark }` and write it in between `\[` and `\]`
