$\"4%5E%282x%29=%281%2F64%29\"$
\n" ); document.write( "64 = 4^3, therefore we can write it:
\n" ); document.write( " $\"4%5E%282x%29=%281%2F4%5E3%29\"$
\n" ); document.write( "the reciprocal
\n" ); document.write( " $\"4%5E%282x%29=4%5E%28-3%29\"$
\n" ); document.write( "therefore
\n" ); document.write( "2x = -3
\n" ); document.write( "x = $\"%28-3%29%2F2\"$
\n" ); document.write( "x = -1.5
\n" ); document.write( ":
