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)
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)
