root of the quotient.

                   

       26244

        / \

       2  13122

          / \

         2  6561

            / \

           3  2187

              / \

             3  729

                / \

               3  243

                  / \

                 3  81

                    / \

                   3  27

                      / \

                     3   9

                        / \

                       3   3

                     

So   26244 = 2238  

To become a cube, all the prime factors of it must  

be to a power which is a multiple of 3.

Notice that the prime number base 2 in the factorization

is raised to the 2nd power (exponent), but exponent 2 is  

NOT a multiple of 3, so we'll have to multiply by the 1st  

power of 2 so that when we add exponents of 2 we will get 23.

Notice also that the prime number base 3 in the factorization

is raised to the 8th power (exponent), but exponent 8 is  

NOT a multiple of 3, so we'll have to multiply by the 1st  

power of 3 so that when we add exponents of 3 we will get 39.

So we have to multiply by 2131

or 2∙3 or 6 to cause 26244 to become a perfect cube.

So we have to multiply 2238 by 2131

so that it will become 2339 and both prime bases 2 and 3

will be raised to powers (exponents) which are both multiples of 3.

So then the cube root of 2339 will be gotten

by dividing each exponent by 3, which will give 2133 which

is 2∙27 or 54.

That's the same as saying

The 26244 must be multiplied by 6 gives 157464 which is a  

perfect cube.  It is a perfect cube because 543 = 157464.

And the cube root is 54 because 54∙54∙54 = 157464.

Answer:

at first

26244 devide by 2=13122

13122devide by 2=6561

6561 devided by 3=2187

2187 devided by 3=729

729 devided by 3=243

243 decided by 3=81

81 decided by 3=27

27 decided by3=9

9devided by3=3

2×2×3×3×3×3×3×3×3×3

thus 26244 decided by 36 to be perfect cube
