\n" ); document.write( "\n" ); document.write( "1. sqrt w-9=8\r
\n" ); document.write( "\n" ); document.write( "2. not sure how to write this problem but it has a 3, then the sqrt sign and inside the sqrt sign is -64.\r
\n" ); document.write( "\n" ); document.write( "3. this one is similar where it has 3 sqrt sign and 16 inside the sqrt. \r

I'll take a stab at them
\n" ); document.write( "\"sqrt%28w-9%29+=+8\"
\n" ); document.write( "sqare both sides
\n" ); document.write( "\"w-9+=+64\"
\n" ); document.write( "Add \"9\" to both sides
\n" ); document.write( "\"w+=+73\"
\n" ); document.write( "--------------
\n" ); document.write( "This one looks like a cube root. When the
\n" ); document.write( "cube root is asked for, they are saying:
\n" ); document.write( "\"What number multiplied by itself 3 times
\n" ); document.write( "will give the number under the cube root sign?
\n" ); document.write( "cube root(\"-64\") = \"-4\" because
\n" ); document.write( "\"%28-4%29%2A%28-4%29%2A%28-4%29+=+-64\"
\n" ); document.write( "---------------------------------
\n" ); document.write( "cube root(\"16\") = cube root(\"8%2A2\")
\n" ); document.write( "cube root(\"16\") = cube root(\"8\") x cube root(\"2\")
\n" ); document.write( "cube root(\"16\") = \"2\" x cube root(\"2\")
\n" ); document.write( "This is because \"8+=+2%2A2%2A2\"
\n" ); document.write( "
\n" );
