A number m is the cube root of a number nif n = m ^{3} .
In other words, the cuberoot of a number n is that number whose cube gives n.
The cuberoot of a number is denoted by ∛n. ∛n is also called a radical, n is called the radicand and 3 is called the index of the radical.
8 = 2^{3} ∴ ∛8 = 2 ;
27 = 3^{3} ∴ ∛27 = 3 ;
343 = 7^{3} ∴ ∛343 = 7 ;
125 = (5)^{3} ∴ ∛(125) = 5 ;
(64/125) = (4/5)^{3} ∴ ∛(64/125) = 4/5 ;
(216) = 6^{3} ∴ ∛216 = 6 ;
(1000) = 10^{3} ∴ ∛1000 = 10 ;












































Remark : The symbol ∛ for the cuberoot is very much similar to the symbol of square root. The only difference is that whereas in the case of square root, we use the symbol '√' for the cuberoot we use the same symbol √ but a 3 which indicates that we are taking cuberoot.
