The details depend on the specific radical expression. Normally, you'll want to:
* Avoid a perfect square under a radical sign. Take it out, by separating the radical into two parts. Example: root (x squared y) = root (x squared) x root (y) = x root (y).
* Avoid a radical sign in the denominator. If you multiply numerator and denominator by the same square root, you get an expression in which there are roots in the numerator, but not in the denominator.
sqrt(216)factor under the radical by dividing by squared numbers. 6 works.sqrt(62 * 6)bring out 6 from under radical6sqrt(6)===========simplified
A radical is an exponent, stupid.
Radical expressions are called like radical expressionsif the indexes are the same and the radicands are identical.
Why is it important to simplify radical expressions before adding or subtracting? How is adding radical expressions similar to adding polynomial expressions? How is it different? Provide a radical expression for your classmates to simplify..
