Identify the properties of exponents and multiplication that apply. When multiplying terms with the same base, you multiply the coefficients and add the exponents of the variables.
Multiply the coefficients: here, multiply -4 and 4, which gives \(-4 \times 4\).
Apply the product rule for exponents to the variable part: since the bases are the same (both are \(x\)), add the exponents \(5\) and \(2\) using \(x^{5} \times x^{2} = x^{5+2}\).
Combine the results from the coefficient multiplication and the exponent addition to write the simplified expression as a product of the new coefficient and the variable with the summed exponent.
Write the final simplified expression in the form \(ax^{b}\), where \(a\) is the product of the coefficients and \(b\) is the sum of the exponents.

Product of Powers Property

When multiplying expressions with the same base, add the exponents. For example, x^a * x^b = x^(a+b). This property simplifies expressions involving powers of variables.
