From
\n" ); document.write( "8^(x+2) = 16^x
\n" ); document.write( "we try to get the bases the same...since 8 = 2^3 and 16 = 2^4, we have
\n" ); document.write( "2^3(x+2) = 2^4x
\n" ); document.write( "and then
\n" ); document.write( "3(x+2) = 4x
\n" ); document.write( "3x + 6 = 4x
\n" ); document.write( "x = 6 \n" ); document.write( "
