Question

reescribir sin paréntesis.
\\((9y^{4}z^{2}-3z^{3})(-4y^{5}z)\\)
simplificar la respuesta tanto como sea posible.

Explanation:

Step1: Distribute the second term

Multiply each term in the first parentheses by $-4y^5z$:
$$9y^4z^2(-4y^5z) - 3z^3(-4y^5z)$$

Step2: Calculate first product

Multiply coefficients and add exponents of like variables:
$$9\times(-4)y^{4+5}z^{2+1} = -36y^9z^3$$

Step3: Calculate second product

Multiply coefficients and add exponents of like variables:
$$-3\times(-4)y^5z^{3+1} = 12y^5z^4$$

Step4: Combine the results

Combine the two simplified terms:
$$-36y^9z^3 + 12y^5z^4$$

Answer:

$-36y^9z^3 + 12y^5z^4$
