The digit in the unit's place of \(5^{834}\) is
- A 0
- B 1
- C 3
- D 5
Answer & Solution
Correct Answer
(D) 5
Step-by-step Solution
Detailed explanation
Now, \(5^{1}=5,5^{2}=25,5^{3}=125, \ldots \ldots\).
Here, we see that in every power of 5 , we get the
unit digit is 5 .
Hence, unit's place of \(5^{834}\) is 5 .
Here, we see that in every power of 5 , we get the
