question
fully simplify.
12x⁵y⁴(-13x⁴y⁴)
answer attempt 1 out of 2

Explanation:

Step1: Multiply the coefficients

$12 \times (-13) = -156$

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

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

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

$y^4 \times y^4 = y^{4+4} = y^8$

Step4: Combine all simplified parts

$-156 \times x^9 \times y^8$

Answer:

$-156x^9y^8$
