Distribute Constant and Multiply: Distribute the constant outside the parentheses across the terms inside the parentheses.We have 4y2 multiplied by each term inside the parentheses (−2x4y5).Calculation: 4y2×−2x4y5
Multiply Constants and Like Terms: Multiply the constants and the like terms.We multiply the constants 4 and −2 to get −8.We multiply the like terms y2 and y5 by adding their exponents to get y(2+5) or y7.We leave x4 as it is because there are no other x terms to combine it with.Calculation: −8×x4×y7
Write Simplified Expression: Write down the simplified expression.The final simplified expression is −8x4y7.
