You can put this solution on YOUR website!
.30 = 7-50+45(1+x)^-.25
\n" ); document.write( "---------------
\n" ); document.write( "0.3 = -43 + 45/(1+x)^0.25
\n" ); document.write( "43.3 = 45/(1+x)^0.25
\n" ); document.write( "(1+x)^0.25 = 45/43.3
\n" ); document.write( "1+x = (45/43.3)^4
\n" ); document.write( "x = (45/43.3)^4 + 1
\n" ); document.write( "x = ~ 2.166537 \n" ); document.write( "

\n" );
