An Easy One


(55^5)/(5^55) = (5 x 11^5)/(5^5 x 5^50)
= (5^5)(11^5)/(5^5)(5^50)
= (5^5)/(5^5) x (11^5)/(5^50)
= 1 x (11^5)/(5^50)
= C

Based on formula a^m/a^n = a^(m-n) and (a*b)^m = a^m * b^n , solving we get C

This is how i solved

55 ^5 / 5 ^ 55

= 11^5 * 5^5 / 5^55
=11^5 * 5^5 / 5^50* 5^5

Cancel 5^5 from numerator and denominator

We get 11^5 / 5^50 ans C
