Question

Check whether 6ⁿ,7ⁿ,4ⁿ can end wíth the dígít 0 for any natural number n.

Answer 1

Step-by-step explanation:

if a no. is divisible by zero it should be divisible by 10.And if it is divisible by 10 it should be divisible by 2&5 as 10=2×5.

now 6n =(2×3)²

it can be seen that 5 does not appear in the prime factorisation of 6n

hence,for any value of n,6n can't be divisible by 10.

therefore,6n can't be end with zero.

Answer 2

Answer:

if a no. is divisible by zero it should be divisible by 10.And if it is divisible by 10 it should be divisible by 2&5 as 10=2×5.

now 6n =(2x3)²

it can be seen that 5 does not appear in the prime factorisation of 6n

hence,for any value of n,6n can't be divisible by 10.

therefore,6n can't be end with zero.
