[1+(1/5)]^n=2?
What is the value of n?

• value of N = 4 (3.8)
  1+1/5 = 6/5 = 1.2
  1.2*1.2 = 1.44 *1.2 = 1.728 *1.2 = 2.0736
  so if N is integer, N=4. if not, N = 3.8
  (1.2)^3.8 = 1.999

• ans
  log(6/5)^n=log2
  n*log6/5=log2
  n*0.079=3.8
  n=3.8/.079=3.81

• hey there is some mistake in my previous solution..the value of log2 should be 0.30....i.e it is 0.30 in place of 3.8..
