Answer: The correct answer is: " 6 ∛3 " .
________________________________________
Step-by-step explanation:
________________________________________
Given: 2 * [tex]\sqrt[3]{81}[/tex] ;
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 " .
