Answer:
No, it is not true.
Step-by-step explanation:
S.T 3^n ×4^m cant end with 0 or 5.
For a number to end with 0, the number
must have 2 & 5 as factors.
10=2×5
100=2² ×5²
For a number to end with 5, the number must have 5 as a factor.
30=5×6
3^n ×(2²)^m =3^n ×2²m
This number dosent have 5 or 5 and 2 as its factors. Therefore the number cant end with 0 or 5.
