Solve for x:
\n" ); document.write( " $\"9%5E%282x%2B1%29+=+243\"$ Find the common base.
\n" ); document.write( " $\"%283%5E2%29%5E%282x%2B1%29+=+3%5E5\"$ Simplify.
\n" ); document.write( " $\"3%5E%284x%2B2%29+=+3%5E5\"$ The bases are equal so the exponents are equal.
\n" ); document.write( " $\"4x%2B2+=+5\"$
\n" ); document.write( " $\"4x+=+3\"$
\n" ); document.write( " $\"x+=+3%2F4\"$ \n" ); document.write( "

\n" );
