Question

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

Answer 1

The correct answer is option A

Explanation:

See the attached figure

Answer 2

Option 1.
`(m^(7)n^(3).n )/(m)` is the correct option.

Explanation:

We have to simplify the expression given by eliminating negative exponents.

expression is
`(m^(7)n^(3)  )/(m.n^(-1) )` 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

`(m^(7)n^(3)  )/(m.n^(-1) ).(n)/(n)=(m^(7)n^(3).n )/(m.n^(-1).n) =(m^(7)n^(3).n )/(m)`

Therefore the answer is
`(m^(7)n^(3).n )/(m)`.
