When 9 ^2/3 is written in simplest radical form, which value remains under the radical?

3

6

9

27

Answer

The value under the radical is 3

Explanation

9^ (2/3) This means 9 squared then find find the cube root of the answer.

9^ (2/3) = ∛ (9^2)

= ∛81

= ∛ (3*3*3*3) = ∛ (3) ³ ₓ ∛3

= 3 ∛3

The value under the radical is 3

I hope this now shows clearly the number under the radical is 3.
