How to simplify radical expressions

Answer 1

Hey there!

To simplify radical expressions, refer to the conversion of a radical expression to a number with an exponent:

$\sqrt[a]{x} = x^{\frac{1}{a} }$

Remember that if you don't see an index, there is an implied "2" that will go where "a" is. 

Depending on your problem, you could also cancel a radical by raising the entire expression by the second power (only if your index is 2). 

Hope this helped you out! :-)
