- Won't it be like this 3600=12 * 12 * 25
Now 12 can be expressed in 18 ways
For 25 there are two combinations possible
1 1 25-----arrangements 3
1 5 5 -----arrangements 3
Total =6
So total= 18*18*6
=1944
Please correct me if i am wrong.

- 12 can be written in 18 ways as product of 3 no.s
so we can write 3600 in more ways hence
(3600*18/12)=5400 - 11 years agoHelpfull: Yes(4) No(7)
- 3600/12*18
=5400 - 11 years agoHelpfull: Yes(3) No(0)

- 3600=(9^1*10^2*4^1)
+1 to powers and then multiplying gives the value
(2+1)(1+1)(1+1)
=12 ways - 11 years agoHelpfull: Yes(0) No(0)
