x^3/y^5

Explanation:

Recall that:

1/a^n = a^-n

This means that y^-5 = 1/y^5.

Thus:
x^3y^-5
=x^3*1/y^5
=x^3/y^5

Here we only have to apply 1 law of indices or exponents formula
i.e:
x^-n=1/x^n

Explanation:

So now here we have x^3y^-5,which can also be written as:
x^3/y^5 (answer)
(note- y^-5 is in the form of x^-n , so can be written in the form of 1/x^n i.e, 1/y^5).
