x⁴ y⁵/z³ y⁶

To simplify the expression x⁴ y⁵/z³ y⁶, we can combine the variables with the same bases and perform the appropriate operations.

First, let's combine the x terms: x⁴/x³ = x^(4-3) = x¹ = x.

Next, let's combine the y terms: y⁵/y⁶ = y^(5-6) = y^(-1) = 1/y.

Therefore, the simplified form of the expression x⁴ y⁵/z³ y⁶ is x / (z³ y).
