    4⋅ (a⋅2)

    2⋅ (4⋅a)

    8a

    Step-by-step explanation:

    (4⋅a) ⋅2

    4⋅ (a⋅2) This is the same by the associative property of multiplication

    2⋅ (4⋅a) This is the same by the associative property of multiplication and the communicative property of multiplication

    4⋅2⋅a⋅2 This brings in an extra 2 so it is not the same.

    8a 4*2 = 8 so this is the same

    4⋅2+a⋅2 This is the not the same 8+2a is not the same as 8a
