write the least number possible with 5 thousands place, use the only the digit 4, 5, 6, 7,8 once

Sagot :

Okay so if we have a number ab,cde then b is the number in the thousands place. So we have: a5,cde 

We want the least number so a<c<d<e since we want the least number for a since it has the biggest place value then:
a = 4;  c = 6; d=7; e=8

Then the least number possible is 45,678.
45678
45768
45867
45876
45786
45687
and many more......
but the least is 45678
