Question 695601
What's expected is probably {{{highlight(log(n,m)=4/3)}}}
That comes straight out of the definition of logarithm.
 
Or maybe you were expected to use the common, base 10 logarithms and take logarithms of both sides, like this:
{{{n^(4/3)=m}}} --> {{{log((n^(4/3)))=log((m))}}} --> {{{highlight((4/3)log((n))=log((m)))}}} <--> {{{highlight(log((n))=(3/4)log((m)))}}}
