I think 64 also

The number of natural numbers which lie between 10.000.000 and 100.000.000
Products of their digits as 6.

The only way to get 6 as a product is
6 as number and product of others 1
61.111.111 ; 16.111.111 ; - - -; 11.111.116 =8 ways

Or Also 3 and 2 as part of that number
32.111.111 ; 31.211.111 etc…8 numbers , 8 positions with 6 identical and equal to 1 and 2 others are 2 and 3

8*7*1*1*1*1*1*1 =56

Hence 56+6=64


I’m ´not sure handle this question in 2 min with this method… please check it

56+8 =54

Edoua
56+8 =54
56+8=64

Sorry
