Question

Plz help D; What is the product? (3a^2 b^4)(-8ab^3) A.-24ab B. -24a^2 b^7 c.-24a^2 b^12 d. -24a^3 b^7

Answer 1

Answer:

d

Step-by-step explanation:

Using the rule of exponents

$a^{m}$ × $a^{n}$ ⇔ $a^{(m+n)}$

Given

(3a²$b^{4}$ )(- 8ab³)

= 3 × - 8 × a² × a × $b^{4}$ × b³

= - 24 × $a^{(2+1)}$ × $b^{(4+3)}$

= - 24 × a³ × $b^{7}$

= - 24a³$b^{7}$ → d
