We can treat the numbers and the pronumerals separately, so #20/4 = 5# and #x^5/x^4 = x#. Our answer is just #5x#.

Explanation:

Not a lot of further explanation needed, but we can divide out the numbers - #20# divided by #4# - to give #5#. Then we can divide out the powers of #x# separately - #x^5# divided by #x^4#. When we divide we subtract indices, so #5-4=1#, and the answer is #x^1#, or just #x#.

Putting those together, we get #5x# as our overall answer.
