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
We know that, \[ \begin{aligned} &5^{1}=5 \\ &5^{2}=25 \\ &5^{3}=125 \text { and so on. } \end{aligned} \] So, unit place is always 5 . So, unit's place of \(5^{834}\) is \(5 .\)
