Simplify each expression.
검증된 단계별 안내1
Identify the expression to simplify: \( (35m^{4}n) \times \left(-\frac{2}{7}mn^{2}\right) \).
Multiply the coefficients (numerical parts) together: \( 35 \times \left(-\frac{2}{7}\right) \).
Apply the product rule for exponents to the variables with the same base: For \(m\), multiply \(m^{4} \times m^{1} = m^{4+1} = m^{5}\); for \(n\), multiply \(n^{1} \times n^{2} = n^{1+2} = n^{3}\).
Combine the results from the coefficients and variables to write the simplified expression as: \( \text{(coefficient result)} \times m^{5} n^{3} \).
Leave the expression in simplified form without calculating the final numerical value, as per instructions.

Multiplication of Monomials
When multiplying monomials, multiply their coefficients (numerical parts) and then multiply variables by adding their exponents if the bases are the same. For example, (a^m)(a^n) = a^(m+n). This rule helps simplify expressions involving variables raised to powers.

Properties of Exponents
The properties of exponents include rules like product of powers, power of a power, and power of a product. Specifically, when multiplying like bases, add the exponents. This is essential for simplifying expressions with variables raised to powers.
