**The parenthesis indicate that it is under the root, if it is not under the parenthesis then it is not under the root symbol**

Example y=√(2x+3)-4 means the 2x+3 is under the root and the -4 is on the outside of the root.

What is under the root and what is not under the root?

• 2x+3 is not under the root and -4 is not under the root

• 2x+3 is under the root and -4 is not under the root

• 2x+3 is not under the root and -4 is under the root

• 2x+3 is under the root and the -4 is under the root

**The parenthesis indicate that it is under the root, if it is not under the parenthesis then it is not under the root symbol**
