Explanation:

Step1: Multiply the coefficients

$(-2) \times (-9) \times 8 = 144$

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

$x^4 \times x^5 \times x^1 = x^{4+5+1} = x^{10}$

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

$s^{10} \times s^3 = s^{10+3} = s^{13}$

Step4: Combine all results

Multiply the coefficient and the combined variable terms.

Answer:

$144x^{10}s^{13}$
