Solve for x, to the nearest thousandth.
\n" ); document.write( " $\"8%5E%282x-1%29+=+90\"$ Is this right? Take the log of both sides.
\n" ); document.write( " $\"Log%288%5E%282x%29%29+=+Log%2890%29\"$ Apply the power rule to the left side.
\n" ); document.write( " $\"2x%2ALog%288%29+=+Log%2890%29\"$ Divide both sides by $\"Log%288%29\"$
\n" ); document.write( " $\"2x+=+Log%2890%29%2FLog%288%29\"$ Evaluate the right side.
\n" ); document.write( " $\"2x+=+1.0269\"$ Divide both sides by 2.
\n" ); document.write( " $\"x+=+0.513\"$ \n" ); document.write( "

\n" );
