Step-by-step explanation:

To find

The difference between the largest and the smallest 3 digit number made by using distinct single-digit prime numbers.

The single-digit prime numbers are 2,3,5,7.

Following are the numbers which we can make using distinct single-digit prime numbers.

753                  573              375                 275

752                  572              372                 273

735                  537              357                 257

732                  532              352                 253

725                  527              327                 237

723                  523              325                 235

Now, the highest 3-digit number using distinct prime number= 753

The smallest 3-digit number using distinct prime number= 235

∴Their difference= 753-235

                            =518.
