Hello!
The answer is:
The second option: 2
[tex]\sqrt[4]{81}=3[/tex]
Why?
We can solve the problem and find the simplified expression using the following root property:
[tex]\sqrt[n]{x^{m} }=x^{\frac{m}{n} }[/tex]
We are given the expression:
[tex]\sqrt[4]{81}[/tex]
Which can be rewrite like this:
[tex]\sqrt[4]{81}=\sqrt[4]{3^{4}}[/tex]
Now, simplifying we have:
[tex]\sqrt[4]{3^{4}}=3^{\frac{4}{4} }=3[/tex]
Hence, the answer is the second option:
[tex]\sqrt[4]{81}=3[/tex]
Have a nice day!
