Which shows the following expression after the negative exponents have been eliminated?

Answer:
Option 1. [tex]\frac{m^{7}n^{3}.n }{m}[/tex] is the correct option.
Step-by-step explanation:
We have to simplify the expression given by eliminating negative exponents.
expression is [tex]\frac{m^{7}n^{3} }{m.n^{-1} }[/tex] where m ≠ 0 and n ≠ 0.
As we know powers of same terms add when we multiply them
Now we multiply numerator and denominator by n then expression becomes
[tex]\frac{m^{7}n^{3} }{m.n^{-1} }.\frac{n}{n}=\frac{m^{7}n^{3}.n }{m.n^{-1}.n} =\frac{m^{7}n^{3}.n }{m}[/tex]
Therefore the answer is [tex]\frac{m^{7}n^{3}.n }{m}[/tex].
The correct answer is option A
