​

Answer 1

Answer:

correct answer is B

plz follow me

Answer 2

Answer:

(ab)²

Option B is correct.

Step-by-step explanation:

We are asked,

(a⁷b³)/(a⁵b) = ?

Now,

We know that,

(a^m)/(a^n) = a^(m - n)

So,

(a⁷b³)/(a⁵b¹) = a^(7 - 5) × b^(3 - 1)

= a²b²

Also, we know that,

a^m × b^m = (a × b)^m

So,

a²b² = (ab)²

Hence,

Option B is correct.

Hope it helped and believing you understood it........All the best
