\[81^\frac{ 1 }{ 4 } = \sqrt[4]{81}\]
can you please explain what it means to "evaluate" that expression? thanks
Use this rule: \( a ^ {\frac{1}{n} = \sqrt[n]{a}} \)
Evaluate simply means to calculate. For example evaluate \(\sqrt{9} \) simply means to calculate \(\sqrt{9} \) which is 3.

ohhh, thanks so much :)
wlcm
81 = 3^4 81^(1 / 4) = (3^4)^(1 / 4) = 3^(4 / 4) = 3
Think of "evaluate" as "eVALUate" or finding the value.
