When simplifying radicals with variables, what happens to variables with exponents that have a remainder when divided by the root?

• The variable is discarded.

• The remainder determines the exponent of the variable inside the radical.

• The variable moves entirely outside the radical.

• The remainder is ignored.

What is the purpose of dividing the exponent by the root when simplifying radicals with variables?

• None of the above.

• To find the new exponent for the variable inside the radical.

• To increase the complexity of the problem.

• To determine how many times the variable will be placed outside the radical.
