Hint: In this problem, we have to find the possible one’s digit of the square root of 9998001 from the give to options. To solve this problem, we have to take the digit at the unit place to check for its square. We should know that when the digit at the unit place is 1, then 1 at unit digit can only be obtained from ${{1}^{2}}$= 1 or ${{9}^{2}}$= 81.

We already know that when the digit at the unit place is 1, then 1 at unit digit can only be obtained from ${{1}^{2}}$= 1 or ${{9}^{2}}$= 81.
Note: Students make mistakes while finding the number one in the united place. We should always remember that when the digit at the unit place is 1, then 1 at unit digit can only be obtained from ${{1}^{2}}$= 1 or ${{9}^{2}}$= 81. We should also know where the unit place is in the given numbers to solve these types of problems.
