SOLUTION IS WRONG

Question:
The remainder when 260  is divided by 5 equals:
Options:
A) 0
B) 1
C) 2
D) None of these
Solution:

Remainder = \(\left [ \begin{matrix}\cfrac{2^{60}}{5}\end{matrix} \right ]\) 

Remainder =\(\left ( \frac {15 + 1 }{5} \right )^{15}\)

By binomial theorem-

remainder =\(\left [ \begin{matrix}\cfrac{1^{15}}{5}\end{matrix} \right ]\) = 1.
