Question 730858
To display {{{log(b,a)}}} you can put log(b,a) inside the curly brackets,
{{{log(4,16^8 inches)=(8inches)*log(4,16)=(8inches)*2=highlight(16inches)}}}
using properties of logaritms ({{{log(b,a^m)=m*log(b,a)}}}) and  {{{4^2=16}}}
Otherwise, you could use properties of powers to think of it as
{{{16^(8inches)=(4^2)^(8inches)=4^(2*(8inches))=4^(16inches)}}}
and the definition of logarithm to go from
{{{16^(8inches)=4^(16inches)}}} to {{{log(4,16^8 inches)=16inches}}}
