Which expression is equivalent to a^4 ⋅ b^2 ⋅ a^‐4 ⋅ b^4?

Varibles do NOT matter. So, we're going to want to find an answer that has either a change of a varible, or the same answer, of course. Therefore, answer is (the last option).

(b^4)

I hope this helps you!

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
