Answer :
Let's solve the given problem step by step for option B:
### B. [tex]$\sqrt[3]{81}$[/tex]
To calculate the cube root of 81, [tex]\(\sqrt[3]{81}\)[/tex], follow these steps:
1. Understand the cube root: The cube root of a number [tex]\(a\)[/tex] is the number [tex]\(b\)[/tex] such that [tex]\(b^3 = a\)[/tex].
2. Apply it to 81: We need to find the number [tex]\(b\)[/tex] such that [tex]\(b^3 = 81\)[/tex].
3. Calculation: The cube root of 81 can be expressed as [tex]\(81^{\frac{1}{3}}\)[/tex].
Through complete calculation, the value of [tex]\(81^{\frac{1}{3}}\)[/tex] is:
[tex]\[ \sqrt[3]{81} \approx 4.3267487109222245 \][/tex]
So, the cube root of 81 is approximately [tex]\(4.3267487109222245\)[/tex].
Regarding option C, it seems there is no specific question provided. If additional information or another specific problem is given, I would be glad to assist!
