12000(1+r)^2=27000
\n" ); document.write( "(1+r)^2=2.25 Divide by 12000
\n" ); document.write( "1+r=2.25^(1/2) Flip the exponent, put in on the other side
\n" ); document.write( " of = sign.
\n" ); document.write( "1+r=1.5 simplify number with the exponent
\n" ); document.write( "r=.5 subtract the 1. \n" ); document.write( "

\n" );
