Answer:

8x^4

Step-by-step explanation:

 22xy6 • (2x3y - 3)

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "y6"   was replaced by   "y^6".  1 more similar replacement(s).

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 (((4 • (x3)) • y) -  6) • 2xy6

Step  2  :

Equation at the end of step  2  :

 ((22x3 • y) -  6) • 2xy6

Step  3  :

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  4x3y - 6  =   2 • (2x3y - 3)

Trying to factor as a Difference of Cubes:

4.2      Factoring:  2x3y - 3

Theory : A difference of two perfect cubes,  a3 - b3 can be factored into

             (a-b) • (a2 +ab +b2)

Proof :  (a-b)•(a2+ab+b2) =

           a3+a2b+ab2-ba2-b2a-b3 =

           a3+(a2b-ba2)+(ab2-b2a)-b3 =

           a3+0+0+b3 =

           a3+b3

Check :  2  is not a cube !!

Ruling : Binomial can not be factored as the difference of two perfect cubes

Multiplying exponents :

4.3    21  multiplied by  21   = 2(1 + 1) = 22

Final result :

 22xy6 • (2x3y - 3)
