A.m^7 n^3 n/m

B.m^7 n^3 mn

C.m^7 n^3/m(-n)

D.m n /m^7 n

Respuesta :

its a i just took the test 

Answer:

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

Step-by-step explanation:

Given:[tex]\frac{m^7 n^3}{m n^-1}[/tex]

Here we have to use exponent rule.

a^-1 = 1/a

So n^-1 = 1/n

Therefore, [tex]\frac{m^7 n^3}{m . \frac{1}{n} }[/tex]

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.

Thank you.
