Cube RootA 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. _______________________________________________________________ 1) If (1331) = 11 ^{3} then ∛1331 = ______ ; 2) If (125/1000) = 5 ^{3} /10 ^{3} then ∛(125/1000) = _________ 3) If (6859) = 18 ^{3} /10 ^{3} then ∛6859 = _________ Cube and CubeRoots • Cube of Numbers • Perfect Cube • Properties of Cube • Cube Column method • Cube  Negative numbers • Cube Rational numbers • Cube Root • Finding cuberoot by Prime Factorization • Cuberoot of Rational numbers • Estimating cuberoot Home Page
