Multiply coefficients and exponents: To simplify the expression {(-9n^9)(n^3)}, we need to multiply the coefficients and add the exponents of the like bases according to the properties of exponents. Calculation: (-9 * n^9) * (n^3) = -9 * n^(9+3) Math error check: Add exponents of like bases: Now we add the exponents of n since they have the same base. Calculation: -9 * n^(9+3) = -9 * n^12 Math error check:
