{\text{In mathematics a cube root of a number }}x\,{\text{ is number }}y\,{\text{such that }}{y^3} = x\,\,\,\,....\left( 1 \right) \\
{\text{now finding the cube root of the number by prime factorization}}{\text{.}} \\
{\text{from the equation one }} \\
{y^3} = 216 \\
y = \sqrt[3]{{216}} \\
{\text{prime factors of are }} \\
{\text{216 = 2}} \times {\text{2}} \times {\text{2}} \times {\text{3}} \times {\text{3}} \times {\text{3}} \\
{\text{now assume three time repeating digits as one}}{\text{.}} \\
{\text{as here by assuming each three as one we will get 2and 3}}{\text{.}} \\
{\text{now we should multiply these numbers}}{\text{.}} \\
{\text{2}} \times {\text{3 = 6 }} \\
\sqrt[3]{{216}} = 6 \\
{\text{which is the cube root of 216 as mentioned}}{\text{.}} \\
{\text{NOTE: whenever you come across this kind of question find out the prime factors of the given number}} \\
{\text{ and always assume the three time repeating digit as one and multiply them to get the cube root }} \\
{\text{ of the number }} \\
