You can put this solution on YOUR website!
185.45 = 32.1 * e^1.23x
\n" ); document.write( "Or
\n" ); document.write( "e^1.23x = 185.45/32.1; divided both sides by 32.1
\n" ); document.write( "e^1.23x = 5.77725856
\n" ); document.write( ":
\n" ); document.write( "Find the nat log of both sides,
\n" ); document.write( "ln(e^1.23x) = ln(5.77725856)
\n" ); document.write( ":
\n" ); document.write( "The log equiv of exponents:
\n" ); document.write( "1.23x * ln(e) = ln(577725856)
\n" ); document.write( "1.23x = 1.753929; remember the ln of e is 1
\n" ); document.write( "x = 1.753929/1.23
\n" ); document.write( "x = 1.42596 (rounded)
\n" ); document.write( ":
\n" ); document.write( "Check our solution on a good calc like a Ti83: enter 32.1* (e^(1.23*1.42596)
\n" ); document.write( "Should get 185.45
\n" ); document.write( ":
