Weegy: 7 3/4 - 3/8 = 31/4 - 3/8; =62/8 - 3/8; = 59/8, as a mixed number 7 3/8
User: x^3y^3 + z^3
Weegy: The answer is "(xy + z) (x^2y^2 - xyz + z^2)."

Solution:
a^3 - b^3 = (a - b)(a^2 + ab + b^2)
y^3 - 27 = (y - 3)(y^2 + 3y + 9)
So, the factored form of y^3 - 27 is (y - 3)(y^2 + 3y + 9).

The expression you provided, x^3y^3 + z^3, cannot be factored further using simple algebraic techniques. It is a sum of cubes, but there is no straightforward factorization formula for the sum of cubes like there is for the difference of cubes.
Therefore, x^3y^3 + z^3 remains as it is and cannot be simplified further.
