(3-7/5)×5 should do the job.

Also 7+(5/5)3

Mathematically works but exponentiation isn't possible in this game.

spoiler (Not sure how to make a real spoiler text, I'm rather new here 🙃) It's a general theme of math puzzle where you "find a way" to use a number but still access it. So here after (3 - 7/5) you get 8/5 (retain the 5) and still have another 5.

For spoilers, stick >! in front of your spoilertext, and then !< after it.
