Question

check whether 4^n can end with digit zero from any natural number'n​

Answer 1

Answer:

No, since 4^odd number will always end in 4, 4^ even number will always end in 6.

Answer 2

Answer:

No, 4^n can never end with 0.

Step-by-step explanation:

Given:- 4^n

To find: Whether 4^n can end with digit zero.

Sol. Let us say for now, 4^n ends with 0

=> 4^n is divisible by 5

=> Prime factorization of 4^n must contain prime '5' but 4^n = (2^2)^n = 2^2n

This means only prime factorization of 4^n is 2.

Hence, 4^n can never end with 0.
