cube root of (-64) = -4,,,,,(-4)^3 = -64
\n" ); document.write( ".
\n" ); document.write( "cube root of (64) = 4,,,,,,,(4)^3 =64
\n" ); document.write( ".
\n" ); document.write( "sqrt (-64) = sqrt(64)*sqrt(-1) = 8i,,,,,,,(8i)^2 = 64i^2 =-64
\n" ); document.write( ".
\n" ); document.write( "remember sqrt(-1) =i,,,,,,i^2 =-1
\n" ); document.write( ".
\n" ); document.write( "sqrt(64) =8,,,,,,,,,,,,,,,,,,,,,,,,,,,,8^2 =64
