Answer 2

Answer:

No, 6^n can't ends with the digit 0 for any natural number n

Step-by-step explanation:

6^1 = 6

6^2 = 36

6^3 = 216

6^4 = 1296

.             .  

.              .

.              .

6^n=......6

here you observed that 6 power anything is ends with 6

and more over

if any number ends with 0 then it's prime factors should be (2*5)^n

but

6^n = (2*3)^n

so,

6^n can't ends with the digit 0 for any natural number n

6^n ends with 6 only...

I think this is from 10th mathematics textbook, chapter 1 exercise may 1.2 or 1.3. I don't remember exactly.

Meanwhile I am 10th student...

ok
