Question

if n is equals to 1, 2, 3 n and so on then 2
power 3 and minus 1 is divisible by which number

Answer 1

Dividend= (Divisor×quotient)+ Remainder

When n is divided by 4 , suppose 'p' is the quotient and remainder=3

Therefore, n=4p+3

2n= 8p+6

When 2n is divided by 4 or when 8p+6 is divided by 4 then remainder =2 and quotient=2p+1
