Converting Radicals to Exponents

Rational Exponents Property

Remember… What is the root of a radical if there is not any number there??

Radicals as Exponents 4) 5) 6) 1) 2) 3)

Example Why 2/3?

Write the given radical using rational exponents.

Questions??

Let’s go the other way! Rewrite as a radical then simplify: 9

This also works with variables… Example 1 (perfect square): Example 2 (with leftovers): Since this is a 3rd root you find three in your “pairs” not just two!

Now let’s solve! Example 3: Example 4:
