You can put this solution on YOUR website!
Assume you mean:
\n" ); document.write( "ln((4x + 9)^2) = 2
\n" ); document.write( ":
\n" ); document.write( "2*ln(4x + 9) = 2; log equiv of exponents
\n" ); document.write( ":
\n" ); document.write( "ln(4x+9) = $\"2%2F2\"$
\n" ); document.write( ":
\n" ); document.write( "ln(4x+9) = 1
\n" ); document.write( ":
\n" ); document.write( "on a calc find the e^x of both sides:
\n" ); document.write( "4x + 9 = 2.71828
\n" ); document.write( ";
\n" ); document.write( "4x = 2.71828 - 9
\n" ); document.write( ":
\n" ); document.write( "4x = -6.28172
\n" ); document.write( "x = $\"%28-6.28172%29%2F4\"$
\n" ); document.write( "x = -1.57
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "Check solution in a calc; enter ln((4(-1.57)+9)^2) = 2.00 \n" ); document.write( "

\n" );
