Are you trying to say that the index of the radical symbol is 4 and the number in the radicand is 81?\r
\n" ); document.write( "\n" ); document.write( "In other words, find the fourth root of 81?\r
\n" ); document.write( "\n" ); document.write( "If that is the case, then ask yourself: What number times itself 4 times, will produce 81?\r
\n" ); document.write( "\n" ); document.write( "How about 3?\r
\n" ); document.write( "\n" ); document.write( "3 x 3 x 3 x 3 = 81\r
\n" ); document.write( "\n" ); document.write( "The root is 3.\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
