perplexus.info :: Numbers : 31 created by 4 successive integers

31 created by 4 successive integers (Posted on 2018-08-13)

Express 31 by 4 successive digits, using no more than 4 out of 5 basic operations (i.e. + - / * and exponentation), nothing else allowed.
No brackets!

The order of the digits must be an arithmetic progression like 8*7-6-5 or 3+4*5+6, examples fitting the specifications but not the result.
