This is a follow up question to this one, which was:

Make the number 1998 using the minimum amount of digits 8.

Your allowed operations are +, -, *, /, ^, % (percent).

You need not use only integers 8: 88 and the likes are acceptable.

You must only use 8 as a digit, nothing else.

This puzzle comes from an old friend's school DMs. He said the best that could be done was 10, so I'm turning to the community to see if you can do it better.

But this time you need to find 38 instead of 1998, still with the least amount of digit 8.

Have fun!

  • $\begingroup$ What does the % operator mean? Edit: Ah, it's just "8%", not an operator. $\endgroup$

  • $\begingroup$ @Clockwork technically, it is a (unary) operator. But you are right, it's just percent. $\endgroup$
