What is the identify element of a radical expression

The video tutorial covers the concept of index and simplification in mathematics, focusing on the identity property. It explains how the NTH root of a number raised to the NTH power equals the original number, using examples with square and cube roots. The tutorial also clarifies the use of radical symbols, emphasizing that if no number is specified, the index is assumed to be two. The session aims to expand students' understanding of roots beyond square roots, introducing cube and fourth roots.

What does the identity property state about the NTH root of a number raised to the NTH power?

• It equals the number itself.

• It equals zero.

• It equals one.

• It equals the square of the number.

If you have the square root of 3 squared, what is the result?

• 3

• 9

• 6

• 1

What is the cube root of X cubed according to the identity property?

• 3X

• X cubed

• X

• X squared

What is assumed if there is no number on the outside of a radical symbol?

• It is a fourth root.

• It is a cube root.

• It is a square root.

• It is a fifth root.

What new types of roots are introduced beyond square roots?

• Cube roots and fourth roots

• Fifth roots and sixth roots

• Ninth roots and tenth roots

• Seventh roots and eighth roots
