Step-by-step Solution
Learn how to solve special products problems step by step online. Expand the expression 4m^7n^4(6m^5n^3+4m^2n^7-5mn^6). Multiply the single term 4m^7n^4 by each term of the polynomial \left(6m^5n^3+4m^2n^7-5mn^6\right). When multiplying exponents with same base we can add the exponents. When multiplying exponents with same base you can add the exponents: -20mn^6m^7n^4. When multiplying exponents with same base we can add the exponents.
