Question

Выполните умножение одночленов: 1. (2p) (-3c²) 2.(-5m²) (-7n)

Answer 1

1) 2p * (- 3c²) = - 6c²p

2) (- 5m² ) * (- 7n) = 35 m²n

Answer 2

1. (2p) (-3c²): To multiply the monomials (2p) and (-3c²), you can simply multiply their coefficients and combine the variables. In this case, the coefficient is 2 times -3, which gives -6. The variables are p and c². When multiplying variables with the same base, you add their exponents. Therefore, the result is -6p c².

2. (-5m²) (-7n): Similarly, to multiply the monomials (-5m²) and (-7n), you multiply their coefficients and combine the variables. The coefficient is -5 times -7, which gives 35. The variables are m² and n. Therefore, the result is 35m²n.
