Identify terms: Identify the terms to be multiplied in the expression −2x4y2(5xy4).The terms are −2x4y2 and 5xy4.
Multiply coefficients: Multiply the coefficients (numerical parts) of the terms.The coefficients are −2 and 5.Multiplying these gives −2×5=−10.
Add variable exponents: Multiply the variables with the same base by adding their exponents according to the rule am⋅an=am+n. For the variable x, we have x4⋅x1 (since x=x1), which gives x4+1=x5. For the variable y, we have y2⋅y4, which gives y2+4=y6.
Combine final expression: Combine the results from the previous steps to form the final simplified expression.The coefficient is −10, the power of x is 5, and the power of y is 6.So the simplified expression is −10x5y6.
