Answer:

Sure, let's simplify the expression step by step.

First, let's expand the expression x y z(x y z-x⁶y²z³-1):

x y z(x y z-x⁶y²z³-1) = x²y²z² - x⁷y³z⁴ - x y z

Now, let's subtract (x⁵y z²-2) (x y z-x²y²z²) from the above expression:

(x²y²z² - x⁷y³z⁴ - x y z) - (x⁵y z²-2) (x y z-x²y²z²)

Simplifying further:

x²y²z² - x⁷y³z⁴ - x y z - (x⁶y³z⁴ - 2x⁵y z² - x²y⁴z⁴ + 2x²y²z²)

Combining like terms:

x²y²z² - x⁷y³z⁴ - x y z - x⁶y³z⁴ + 2x⁵y z² + x²y⁴z⁴ - 2x²y²z²

Simplifying again:

- x⁷y³z⁴ + 2x⁵y z² + x²y⁴z⁴ - x²y²z² - x y z

And that's the simplified expression after subtracting the given expression.
