Let's make up a cubic of this form with one root we know, say #x=2.# #8 + 6p = 2q # We'll skip #p=-1, q=1# because #q^2+p^3# isn't negative. 3 cubed is 27, so the cube root of 27 is 3 Step 1. Notice that the symbol for cube root is the radical sign with a small three (called the index) above and to the left . To check if 3 is a factor of a number, sum the digits of the number and divide the sum by 3. The cube root of any number is denoted with the symbol ∛. 8, then cube root will have unit digit as 2. Cube Root. Cube root of a number gives a value, which results in the original number when multiplied by itself thrice. 3375 ends with 5, which is an odd number, so 2 is not a factor of 3375.
