fully simplify.
$-10x^{5}y^{2}(-3x^{4}y^{4})$

Explanation:

Step1: Multiply constant coefficients

$(-10) \times (-3) = 30$

Step2: Multiply $x$-terms (add exponents)

$x^5 \times x^4 = x^{5+4} = x^9$

Step3: Multiply $y$-terms (add exponents)

$y^2 \times y^4 = y^{2+4} = y^6$

Step4: Combine all simplified terms

$30 \times x^9 \times y^6$

Answer:

$30x^9y^6$
