Is 6 to power n divisible by 5
Asked by DHARVI A. BHATT | 20th Jul, 2010, 12:00: AM
Expert Answer:
Dear Student
6n is not divisible by 5.
Since prime factorisation of 6n = (2x3)n
=2n x3n which does not contain 5
Prime factorisation is unique according to Fundamental Theorem of Arithmetic.
So 6n cannot be divisible by 5 for any n
