$\"7root%283%2C+6%29-+2root%283%2C+6%29\"$
\n" ); document.write( "As the problem says, only like radicals can be added or subtracted. Like radicals have the same index and the same radicand. (The expression inside a radical is called the radicand.)

\n" ); document.write( "Your radicals have the same indices (\"indexes\"), 3, and the same radicand, 6. So we can subtract them.

\n" ); document.write( "Now that we know that we can subtract we have to know how to subtract these terms. It can help to picture the radicals as a variable because subtractions (or additions) with variables is just like subration (or addition) with radical terms.
\n" ); document.write( "So exactly like 7x - 2x = 5x...
