    n is index so you can try all options one by one for example first one replace n with n |dw:1442011513344:dw| now take 4th root if you get equal sides then 4 would be ur answer

    oh alright so you can convert root to an exponent form \[\huge\rm \sqrt[n]{x^m}=x^\frac{ m }{ n }\] |dw:1442011674088:dw| now you have to write 16807 in terms of 7 base
