Answer: The correct answer is: " 6 ∛3 " .

________________________________________

Explanation:

________________________________________

Given: 2 *
\sqrt[3]{81} ;

Simplify this given expression:

Let us list the factors of: 81:

1, 2, 3, 9, 27 , 81 .

________________________________________

Are any of these factors "perfect cubes"?

Let's see: ∛27 = 3 ; (use calculator); since: " 3³ = 3 * 3 * 3 " .

81 = 27 * 3 ;

So: " ∛(81) " ;

= ∛(27) * ∛(3) ;

= " 3 * ∛3 " ;

________________________________________

→ The original expression:

" 2 * ∛81 " ;

________________________________________

= 2 * 3 * ∛3 ;

= (2 * 3) * ∛3 ;

= 6 ∛3 .

________________________________________

The answer is: " 6 ∛3 " .

Hope this answer is helpful to you!

Wishing you the best!
