Identify Terms: Identify the terms in the expression that can be combined.We have the expression 16x5y5(9y4). We can combine the constants (16 and 9) and the like terms (y5 and y4).
Multiply Constants: Multiply the constants together. 16×9=144
Apply Product Rule: Apply the product rule for exponents to combine the y terms.The product rule states that when multiplying like bases, you add the exponents: y5×y4=y5+4=y9.
Combine Results: Combine the results from Step 2 and Step 3 with the remaining term x5. The fully simplified expression is 144x5y9.
