From
\n" ); document.write( "5^(2x+1) ≥ 50
\n" ); document.write( "take the log of both sides and then use the power rule, before solving...we get
\n" ); document.write( "log(5^(2x+1)) ≥ log 50
\n" ); document.write( "(2x+1)*log 5 ≥ log 50
\n" ); document.write( "2x + 1 ≥ log 50 / log 5
\n" ); document.write( "2x ≥ (log 50 / log 5) - 1
\n" ); document.write( "x ≥ [(log 50 / log 5) - 1] / 2
\n" ); document.write( "or
\n" ); document.write( "x ≥ .7153 \n" ); document.write( "

\n" );
