99^n , What is the value of n such that the number starts with 8.

• for n=1 value=99
  for n=2 value=9801
  for n=3 value=970299 and so on
  
  here we can see that for every increase in n ..the second digit of the value is decreasing by 1... lyk 99, 9801, 970299
  
  therefore the values will go lyk( i m writing only the first two digits)
  
  n=1 value=99
  n=2 value=98..
  n=3 value=97..
  n=4 value=96..
  n=5 value=95..
  n=6 value=94..
  n=7 value=93..
  n=8 value=92..
  n=9 value=91..
  n=10 value=90..
  n=11 value=8..
  
  hence value of n=11

• 99^n
  99^1= 99
  99^2= 9801
  99^3= 970299
  take only starting two digit, other digit will not change the solution..
  =99*98*97*96*95....
  =99*98*97*.....*89
  so 11 will be the correct solution :)
