20x³y⁵÷50x²y³

To simplify the expression 20x³y⁵ ÷ 50x²y³, we can divide the coefficients and subtract the exponents of the variables.

First, let's divide the coefficients: 20 ÷ 50 = 2/5.

Next, let's subtract the exponents of the variable x: 3 - 2 = 1.

Lastly, let's subtract the exponents of the variable y: 5 - 3 = 2.

Therefore, the simplified expression is (2/5)x¹y² or 2/5xy².
