Bot GPT 4-o mini To find the cube root of 81, we are looking for a number that, when multiplied by itself twice (i.e., cubed), gives us 81.
In mathematical terms, we want to solve:
\[ x^3 = 81 \]
We can express this as:
\[ x = \sqrt[3]{81} \]
Calculating this gives:
\[ \sqrt[3]{81} \approx 4.326 \]
Since this is not one of the options given, let's review the choices:
- 27
- 9
- \( \sqrt[3]{81} \)
- -9
The correct answer is \( \sqrt[3]{81} \), or approximately 4.326, but with respect to the provided options, the best choice is:
\[ \sqrt[3]{81} \]
Thus, if we are to select from the given options, the updated answer is:
\(\sqrt[3]{81}\)
