Solve for x:
\n" ); document.write( "\"%282%5Ex%29%2A%288%5E%28x%2B1%29%29+=+16%5E%281%2F3%29\" Replace: \"8+=+2%5E3\" and \"16+=+2%5E4\"
\n" ); document.write( "\"%282%5Ex%29%2A%282%5E3%29%5E%28x%2B1%29+=+2%5E%284%281%2F3%29%29\" Simplify.
\n" ); document.write( "\"%282%5Ex%29%2A%282%5E%283x%2B3%29%29+=+2%5E%284%2F3%29\" Add the exponents on the left side.
\n" ); document.write( "\"2%5E%284x%2B3%29+=+2%5E%284%2F3%29\" Since the bases (that's 2) are equal, the exponents are equal, so...
\n" ); document.write( "\"4x%2B3+=+4%2F3\" Multiply through by 3 to clear the fraction.
\n" ); document.write( "\"12x%2B9+=+4\" Subtract 9 from both sides.
\n" ); document.write( "\"12x+=+-5\" Divide by 12.
\n" ); document.write( "\"x+=+-5%2F12\"
\n" ); document.write( "Check:
\n" ); document.write( "\"%282%5Ex%29%2A%288%5E%28x%2B1%29%29+=+16%5E%281%2F3%29\" Substitute x = -5/12
\n" ); document.write( "\"2%5E%28-5%2F12%29%2A%288%5E%287%2F12%29%29+=+16%5E%281%2F3%29\"
