Answer:

10000 different numbers

Step-by-step explanation:

The numbers will have the form 1XXXX5, in this case, the order is important because 123465 is a different number to 123645. To know the total of differents decimal numbers, use the formula of permutation with repetition:

n^r

n is the number of options, n=10, and r the number of times you have to place a digit, r=4.

10^4=10000
