You can put this solution on YOUR website!
sqrtx~3=8 or squaring both sides we get x~3=64 or x=4 \r
\n" ); document.write( "\n" ); document.write( "proof sqrt4*4*4=8 sqrt64=8 or 8=8 \r
\n" ); document.write( "\n" ); document.write( "3sqrtx~2=4 or 3sqrt(x*x)=4 3*x=4 or x=4/3\r
\n" ); document.write( "\n" ); document.write( "proof 3sqrt4/3*4/3=4 or 3*4/3=4 or 12/3=4 or 4=4
