Identify Terms: Identify the terms to be multiplied in the expression −3x5y4(2y3). We have a constant −3, a term with xx5, and two terms with yy4 and 2y3.
Multiply Constants and Like Terms: Multiply the constants and the like terms separately.First, multiply the constants −3 and 2 to get −6.Then, since the bases are the same for the y terms, add the exponents 4 and 3 to get y(4+3).
Combine Results: Combine the results from the previous step.We have −6 from the constants, x5 from the x term, and y7 from the y terms.So, the expression becomes −6x5y7.
