Answer:

# (8*z^4+y^3) * (-8*z^4+y^3) #

Explanation:

To solve this problem you must think what can i factor for the y^6

Since the rule of exponent is y^6

(y)^3 * (y^3) add them
so y^6

Think of it as y^2
(y) * (y) = y^2
To get 64
what is it divisible by?
Check if it is divisible by 2 to get perfect squares if not
2 * 2 = 4 until 8*8 = 64
So you got the second one.
The factor of z can be the same as above
which is (z^4) (z^4) and then you add them to the parenthesis.
In any order.
