# Write the following sets in the set-builder form $C=\{5,25,125,625\}$

$\begin{array}{1 1}(A)\;C=\{x : x=5^n,n\in N\;and\;N \leq 4\}\\(B)\;C=\{x : x=2^n,n\in N\;and\;N \leq 4\}\\(C)\;C=\{x : x=3^n,n\in N\;and\;N \leq 2\}\\(D)\;C=\{x : x=6^n,n\in N\;and\;N \leq 8\}\end{array}$

Can you answer this question?

$C=\{x : x=5^n,n\in N\;and\;N \leq 4\}$
Hence (A) is the correct answer.
