Guys please help! It would mean a lot if you guys tell me how did u get the answer as well.

Answer:
[tex]24a^{9}b^{4}[/tex] , so I believe the first option!
Step-by-step explanation:
6 x a to the 7th x b to the 3rd x 4 x a to the second x b =
6 x 4 x a to the (7 + 2) power x b to the (3+1) power =
[tex]24a^{9}b^{4}[/tex]
Hope that helps!
Answer:
24a^9b^4
Step-by-step explanation:
When finding the area of a rectangle, you need to multiply the length by the width:
(6a^7b^3)(4a^2b)
6 times 4 is 24.
When we multiply exponential numbers, we add their exponents:
(a^7)(a^2)=a^9
and
(b^3)(b^1)=b^4
So our completed answer is:
24a^9b^4
HTH :)
