Apologies for the incorrect response. Let's solve correctly now.
To find the cube root of 81, we need to find a number that, when multiplied by itself three times, equals 81.
Let's check the options provided:
- 9 cubed (9^3) is equal to 729, which is greater than 81.
- 27 cubed (27^3) is equal to 19683, which is also greater than 81.
- -9 cubed (-9^3) is equal to -729, which is less than 81.
- The option "81−−√3" is not a valid mathematical expression.
The correct answer is 9. The cube root of 81 is 9.
