I hope it's helpful please mark me as brainliast.

Step-by-step explanation:

To form the largest number we must arrange in descending order:

So, largest four digit number formed by the digits 4,0,3,7=7430

To form smallest digit number by the digits, we must arrange in ascending order by keeping '0' in the second place from left side:

So, smallest four digit number by the digits 4,0,3,7=3047.

Answer 2

Answer:

by using 1,2,3,4 the greatest 4-digits number = 4321

the smallest number = 1234

difference between the 2 numbers

=> 4321 -- 1234 = 3087

ans: 3087
