You can put this solution on YOUR website!
f(x)= 6434x to the -4/3 power. x=18
\n" ); document.write( ":
\n" ); document.write( " $\"f%28x%29=6434x%5E%28-4%2F3%29\"$
\n" ); document.write( ":
\n" ); document.write( " $\"f%28x%29=6434%2A18%5E%28-4%2F3%29\"$
\n" ); document.write( "reciprocal gets rid of the negative exponent
\n" ); document.write( "f(x) = $\"6434%2F%2818%5E%284%2F3%29%29\"$
\n" ); document.write( ":
\n" ); document.write( "find 18^(4/3) on a calc
\n" ); document.write( "f(x) = $\"6434%2F47.1733\"$
\n" ); document.write( ":
\n" ); document.write( "f(x) = 136.39
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "You can check this on a calc; enter: 6434*18^(-4/3) = 136.39 \n" ); document.write( "

\n" );
