Identify Coefficients and Like Terms: Identify the coefficients and the like terms.In the expression (−2m4)(5m3), the coefficients are −2 and 5, and the like terms are m4 and m3.
Multiply Coefficients: Multiply the coefficients.Multiply −2 by 5 to get the new coefficient.−2×5=−10
Apply Product Rule for Exponents: Apply the product rule for exponents.When multiplying like bases, add the exponents: m4×m3=m4+3=m7.
Combine Results: Combine the results.Combine the new coefficient from Step 2 with the result from Step 3 to get the final simplified expression.−10×m7=−10m7
