Distribute Constant: Distribute the constant outside the parentheses across the terms inside the parentheses.We have 13x3 multiplied by each term inside the parentheses, which is −9x5y4.Calculation: 13x3×(−9x5y4)
Multiply Constants: Multiply the constants 13 and −9.Calculation: 13×−9=−117
Apply Product Rule: Apply the product rule for exponents to multiply x3 and x5. The product rule states that when multiplying like bases, you add the exponents. Calculation: x3×x5=x3+5=x8
Combine Like Terms: Since there is no other y term to combine with y4, we simply carry it over.Calculation: y4 remains unchanged.
Final Simplified Expression: Combine the results from steps 2, 3, and 4 to get the final simplified expression.Calculation: −117×x8×y4
