3 index square root 81

I got the answer 3 3index square root 3 is this correct?

isnt the square root of 81 equal to 9.

3*9=?

If this is what you mean,

cube root = cr

(cr(81)) = (cr(27))*(cr(3))
(cr(81)) = 3*(cr(3))
(cr(81)) = 3(cr(3))

This can be written as
81^(1/3) = 3(3^(1/3))
81^(1/3) = (3^(3/3)*(3^(1/3))
81^(1/3) = 3^(4/3)

To find the 3-index square root of 81, we need to raise 81 to the power of 1/3. This is because the 3-index square root is the value that, when raised to the power of 3, gives us 81.

So, using a calculator or any mathematical software, you can compute 81^((1/3)) to get the answer.

Simplifying this expression, we have 81^(1/3) = 4.3267487109.

Therefore, the correct answer is approximately 4.33. It seems like you made a small rounding error in your calculation.
