Question 3 unsaved factor as the sum of cubes: 27x12+8y3 question 3 options: (3x6+2y)(9x16−6x4y+4y2) (x4+2y)(x8−6x4y+4y2) (3x4+2y)(9x8−6x4y+4y2)

The correct answer is the third one (3x4+2y) (9x8-6x4y+4y2).  

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
