Is it already in standard form

To make it standard form, you'll have to reorder the terms by descending powers. Remember to bring the signs with the right monomials
-2a^5 + 4a^4 + 5a^3 + 2/3a, or (C) is your answer
hope this helps
Hi!
So you need to put it in ddescending order which means the exponents have to decrease every term.
The original have 1, 2, 3, 4, 5
but you want it to have 5, 4, 3, 2, 1
So the answer is C!
Hope this helps!
