Answer 1

Its a i just took the test 

Answer 2

Answer:

A) (m^7 n^3 n) / m

Step-by-step explanation:

Given:$\frac{m^7 n^3}{m n^-1}$

Here we have to use exponent rule.

a^-1 = 1/a

So n^-1 = 1/n

Therefore, $\frac{m^7 n^3}{m . \frac{1}{n} }$

If we have fraction in the denominator, we can flip and multiply, so we get

= (m^7 n^3 n) / m

Answer is  A) (m^7 n^3 n) / m

Hope this will helpful.
