solve:
\n" ); document.write( "(4*x+51)^(1/3)=5\r
\n" ); document.write( "\n" ); document.write( "first, eliminate the cube root by raising the equation to the third power:
\n" ); document.write( "(4*x+51)=5^3
\n" ); document.write( "4*x+51=125
\n" ); document.write( "subtract the 25 from both sides:
\n" ); document.write( "4x=74
\n" ); document.write( "then divide by 4 both sides
\n" ); document.write( "x=18.5
\n" ); document.write( "-54 is wrong???? \n" ); document.write( "

\n" );
