Hi,  
{{{f(x)=1/512 = 1/8^3 = (8^0)/(8^3) =8^(0-3) =   8^(-3 )}}}
As to 512 being 8^3 ... some just know that...
others arrives at that by experimenting dividing 512 by logical selections.. like an 6 or 8
{{{a^0 = 1}}}  ******
{{{(a^p)^q = a^(p*q)}}}
{{{root(a,p)*root(a,q) = root(a,p*q)}}}
{{{x^m/x^n=x^(m-n)}}}********
{{{( x^m )( x^n ) = x^( m + n )}}}
