Q2 no

Step-by-step explanation:

No. This your answer

Answer 2

Answer:

No

because if 4^2021 ends with 0 then it must have 5 as a factor. but 4^2021=(2^2)^2021 shows that 2 is the only prime factor of 4^2021

Also,we know from the fundamental theorem of arithmetic that the prime factorisation of each number is unique.

So,5 is not a factor of 4^2021

Hence,4^2021 can never end with the digit 0
